Priora generator brushes: how to replace them correctly and do it yourself

If the owner of a Priora notices that the battery is no longer charging, then first of all you need to check the condition of the generator brushes. It is worth noting that at first the battery charge will decrease slightly, but if the problem is not corrected in a timely manner, the battery charge will soon disappear altogether. Replacing the worn brushes of the Priora generator will help correct this problem. And since this process is not so complicated, you can carry out such work yourself, taking into account advice from professionals in your field. Subscribe to the channel - .

On automobile forums you can often see complaints from Lada owners with air conditioning about increased current. It is worth saying right away that the current cannot be increased - this applies to voltage. If the instruments show you that the current in the generator is too high, then you need to look for a problem in the relay.

If you chose the complete replacement method, all you have to do is install the new part and assemble all the elements in the reverse order. In any case, we recommend that you at least check the generator bearings and the condition of the collector plates. If the wear of the plates is within normal limits, before installing new brushes, clean the surface to a shine with fine-grained sandpaper.

If you need to replace a Priora generator with air conditioning, then there are two nuances that lie in the manufacturer of the air conditioner. Panasonic allows you to remove the unit without a compressor, but the Hull compressor will not allow you to get the generator. Replacing generator brushes on a Priora with air conditioning.

As is known, maintaining charging at the same level is carried out by adjusting the voltage supplied to the generator armature winding. For reliable contact, the brush leads are attached to the contacts of the voltage regulator relay by soldering.

To simplify car repairs, brushes, brush holder and relay regulator are most often sold assembled. The advantage of the complete replacement method is its simplicity. For example, the low cost of the assembly for many VAZ cars makes separate replacement of brushes very impractical. Well, there you are...

Priora generator brushes: how to replace them correctly and do it yourself

If the owner of the Priora notices that the charge from the battery is disappearing, first of all, he needs to check the condition of the generator brushes. Of course, at first the charge decreases insignificantly, but if the problem is not corrected in time, the charge will very soon disappear altogether. Replacing the brushes of the Priora generator, which are clearly worn out, will help correct this problem.

Important! The brush mechanism of the generator on the Priora cannot be repaired. If any breakdown occurs, only a replacement along with the brushes will be required.

Since this process is not so complicated, you can do everything yourself. You just need to take into account the recommendations of professionals.

What tools are needed for work?

Before changing the brushes on the generator, prepare the tools you will need for the job:

flat screwdriver;
wrench – it’s better if it’s an open-end wrench (size 13);
car head with wrench (size 10).

Changing the generator brushes, process sequence

It is quite possible to replace the alternator brushes on a Priora that have worn out without removing it. But, according to experts in their field, the process is simplified if replacing the generator is preceded by removing it from its usual location.

Important! When carrying out any work on the generator (replacement, repair, etc.), be sure to disconnect the battery.

After removing the generator on the Priora, replacement is carried out as follows:

Use a screwdriver to remove the plastic cover, which is designed to protect the device. Having done this, you gain access to the brushes;
disconnect the connecting plug from them;
slowly unscrew both fasteners (they are located along the edges of the elements that are inspected);
Take the above key and unscrew the locking bolt. Do this in the center of the element;
Having unscrewed all the fasteners, remove the brushes, inspect them, assess their condition and replace them with new ones, connect the wires.

What are the signs that indicate that the generator brushes have become unusable?

The following external “signs” will help with this:

if, upon examining this element, you find that its length is less than 5 mm, it certainly requires replacement;
if the brushes are worn unevenly, this will also negatively affect the functioning of the generator, so they need to be replaced.

There is no need to skimp on buying new brushes. If you find a cheap option, it is highly doubtful that they will last long. It is more likely that such savings will lead to the need to re-replace the above-mentioned components.

Reassembly

After purchasing high-quality brushes (it is advisable that your choice falls on a well-established manufacturer), you can begin the general assembly of the element, and then install the generator itself in its place. However, as mentioned above, the last procedure can be performed without removing the generator. Which, however, is decided independently by each car owner. All operations performed should be performed in reverse order. After completing the work, the operating efficiency of the entire generator must be checked.

You should use a voltmeter to check whether the charging process is moving, as well as what the panel displays. Make sure its work is objective. Indicators that correspond to each other are evidence that the remaining elements can be installed in their places and the generator repair has been completed successfully.

If the replacement of failed brushes was carried out correctly, and the battery was discharged precisely because the main elements of the car’s electrical system were worn out, the car owner will solve this problem without the help of service station workers. And in this case, you will save a lot on such a service. The replacement process is really quite simple. However, if you encounter any difficulties during the repair work, you can watch the help video. It is provided by specialists. On the Internet resource you can, among other things, find out:

about design features - generator 2170;
how to check the generator for operability, what you should pay special attention to;
how to change wipers on a Priora and so on;
What other possible problems can occur with the power generator?

Generator on a car with air conditioning compressor

On a vehicle equipped with air conditioning, the air conditioning compressor and alternator are driven by a single belt. The air conditioning compressor, its tubes and hoses make it difficult to remove the generator. To remove the generator, it is necessary to disconnect the compressor from its mounting bracket.

An inspection ditch or overpass will be required to complete the work.

1. Remove the engine splash guard.

2. Remove the drive belt of the generator and compressor.

3. From the top of the engine compartment, remove the rubber cover from the contact bolt (terminal B +).

4. Use a 10 mm wrench to unscrew the contact bolt nut.

5. Remove the wire tip from the contact bolt.

6. Disconnect the wires from terminal D of the generator.

7. Using a 13 mm spanner, unscrew the nut of the bolt of the upper mounting of the generator, holding the bolt with a wrench of the same size.

8. Remove the bolt.

9. From the bottom of the engine compartment, using a 17 mm spanner, unscrew the bolt of the lower mounting of the generator.

10. Using a 12 mm spanner, unscrew the four bolts securing the air conditioning compressor (the lower right bolt, shown in the photo, is short, and the other three are long).

11. We move the compressor down and towards the right side member of the body until it stops, without disconnecting the air conditioning system pipes.

There is no need to mount the compressor. It is held securely by surrounding parts.

12. Remove the bolt from the generator bracket along with the metal sleeve.

13. Remove the generator.

Install the generator in reverse order.

Replacing generator brushes on VAZ-2113, 2114, 2115

The generator brushes serve as conductors of electric current: they supply and discharge it.
Thanks to their work, the generator generates voltage, which contributes to the stable functioning of the car’s electronic mechanisms. Brushes are made of graphite, carbon parts are especially popular, and for engines operating at high speeds, the brushes are impregnated with a special composition, which prevents them from becoming unusable ahead of time.

Basic faults

The primary reason for the breakdown of generator brushes is their wear, which makes itself felt by a poor battery charge. You can detect a failed part by the following problems:

voltage failures;
the battery discharges quickly or does not charge at all;
the headlights begin to burn much weaker or blink;
instrument lights blink;
There is not enough voltage for the electronics to operate and it turns off (radio tape recorder, for example).

Why change brushes?

If signs of brush breakage are detected, they should be replaced.
If repairs are not carried out in a timely manner, there is a possibility that you will soon need to purchase a new generator, and this is a completely different expense. The battery can only hold the ignition without brushes for a few minutes, which means it will have to be constantly charged. And soon it will be replaced. You can check the condition of the brushes by the size of their protrusion from the seat. If the protrusion size does not reach five millimeters , then they should be replaced immediately to avoid possible problems.

It is recommended to replace it every 50,000 km or every season, which is the key to safe operation of the vehicle. It is better to have a spare set of spare parts so as not to get into an unpleasant situation on the road and then call a tow truck.

For a set of brushes you will need to pay from 150 to 200 rubles, depending on the store. The cost of repairs at a car service center will cost 200-300 rubles, inexpensive, of course, but why pay for something that you can do yourself?

Replacement

The process of replacing old brushes with new ones does not take much time and does not require special knowledge. The only thing you need to prepare are the tools:

socket wrench 13;
flat screwdriver (ordinary);
8mm socket with ratchet.

Without removing the generator

If you are sure that the problem with the car breakdown is a malfunction of the generator brushes, then you can do without removing it.

Turn off the negative terminal.
Disconnect the wires.
On the brush holder body, unscrew the two bolts holding it in place.
We extract the structure.
We check for damage and the size of the protruding part of the brushes (it must be at least 5mm).
We install new elements and carry out installation in the reverse order.

With the generator removed

Poor charging of the car can be caused not only by the brushes, but also by the alternator belt. To eliminate this point, when replacing brushes, you should remove it to check the condition of the belt.

First, we dismantle the unit.

We unscrew the bolt securing the generator belt.
Move the unit towards the engine and remove the belt.
Unscrew the tensioner bar and remove it.
Disconnect the plug and terminals.
We take out the part.

Let's move on to the brushes

Open the protective casing (cover).
Disconnect the brush power wires.
We unscrew the two bolts securing the element we need.
On the right side, using a 13mm wrench, unscrew one nut.
The voltage regulator should be raised.
We check the old brushes.
We clear their location.
We install new elements and assemble everything in reverse order.

Replacement result

After replacement, errors may appear about a low battery charge or a malfunction of the generator; there is no need to immediately try to find the cause of the failure. This phenomenon is not uncommon, since new brushes have just begun to break in. After some time, everything will return to normal, and you can safely continue using the car.

How to check a generator on a car without removing it Our review

When the engine is running, the light that monitors the battery charge is either constantly on or blinking.
The battery spontaneously discharges or boils away;
The headlights shine dimmer than they should;
The operation of the motor is accompanied by rattling or a low, continuous squeak. Alternatively, the generator may howl;
As the engine speed increases, the brightness of the headlights increases sharply. This phenomenon is considered normal when revving at idle speed. However, once the headlights reach normal brightness, the intensity should no longer change. If you accelerate - they burn brighter, release the pedal - they dim, which means the generator is clearly unhealthy.

The generator drive belt is inspected. The degree of tension is controlled; If delaminations, tears or cracks are detected, the belt is immediately replaced. In some situations, more complex actions are not required;
The fuse is checked - like any other, it quite often fails;
Next, you need to make sure that the rotor rotates freely, the wires are not pinched or frayed anywhere, the contacts have not come loose, and the housing is not cracked;
The charging relay is replaced with a new one - this is the easiest way to make sure that everything is in order with it. In most cases, a visual inspection cannot give complete confidence in its performance.

The engine starts. The meter remains connected to the battery;
All the electrics on board start to work randomly: the heater turns on, the headlights turn on/off, more gas is periodically given, you can turn on the audio system;
During the described executions, testimony is taken. If the voltage remains stable between 14 and 14.2 V, your difficulties are not caused by the generator. If jumps of no less than 0.5 V are noticed (and usually they reach 1 V), you have a direct path to a specialist who will find what has gone wrong in this node;
Bearings can fail (it is they that cause the whine and whistling of the generator); the reason for the non-working condition can be clogged or worn out generator brushes, worn or again clogged rings.

How to change the generator on a Priora?

The generator in the car allows the battery to charge while driving and powers the entire on-board network; if it malfunctions, the car will only drive until the energy reserve in the battery is used up. As soon as this happens, the car will stall, so if a fault is detected in the generator, you should immediately go to a service center or park the car near the house to figure out how to change the generator on a Priora. This is easy to understand; everything will be immediately displayed on the battery charge lamp; if it lights up on the panel, this is a clear signal that it’s time to go for repairs. Or - do everything yourself. If all else fails, you can contact a car pawnshop)))

Generator

The Lada Priora car has a three-phase alternating current generator with electromagnetic excitation, a diode rectifier unit and a built-in voltage regulator.

The generator is driven by a poly V-belt from the crankshaft pulley. On a car with an engine without auxiliary units (air conditioning compressor or power steering pump), the generator is attached to the engine on two brackets. The upper bracket is equipped with a tension bar that allows you to adjust the tension of the generator drive belt. On a vehicle with an air conditioning compressor or power steering pump, the generator is mounted on one bracket. Additionally, there is a small oval hole in the upper eye of the bracket, which allows you to tighten the drive belt by moving the generator. A drive belt tension roller is installed at the end of the cylinder block. To adjust the belt tension, the axial hole of the roller is made with a radial offset. Continue reading →

Do-it-yourself removal and disassembly of a VAZ generator

Generator 2110 is a part without which the operation of the car is impossible. Its condition must be checked every maintenance (15 thousand km). If during the diagnostic process of the generator, comments were identified, they must be addressed urgently. Let's look at how to remove the generator yourself, as well as disassemble it (remove the voltage regulator, diode bridge and bearings).

Replacing the VAZ 2110 generator

Disconnect the generator excitation wire.
Unscrew the nut securing the wires to terminal “B+” using a “10” wrench.
Remove the “B+” terminal wires.

Remove the generator tension bar.
Unscrew the nut of the lower mounting of the generator using a “13” wrench.
Remove the mounting bolt.
Remove the tens generator.

Removing the generator voltage regulator

Release the 3 spring clips and remove the protective cover of the generator diode bridge.
Unscrew the 2 screws securing the voltage regulator using a Phillips screwdriver.
Disconnect the block with the wire from the output of the relay-regulator and remove it.

Removing the diode bridge from the generator

Unscrew 3 bolts that connect the terminals of the stator windings to the rectifier block (1) using an 8-mm spanner, and 1 more bolt holding the diode bridge (2). Remember how the isolating and thrust washers are installed.
Bend the wires of the stator winding leads to the side.
Unscrew the capacitor mounting screw using a Phillips screwdriver.
Remove the diode bridge along with the capacitor. Unscrew the 2 contact bolt nuts using a 10mm socket wrench. Remove the spacer and insulating bushings from the bolt, remove the bolt from the diode bridge and the capacitor tip from the contact bolt.

Replacing the front and rear bearings of the generator

Before removing the front and rear covers of the generator, you should mark their location with a marker.
Unscrew the 4 bolts using an 8mm socket wrench.
Open the generator covers using a flathead screwdriver.
Disconnect the back cover from the front along with the stator winding.

To remove the front bearing of the generator, you need to attach a suitable object to it, for example, a “27” socket. Then knock it out with hammer blows.
Lubricate the bearing seat.
The front bearing is installed using the old one. Place it on top and carefully drive the bearing in a circle.
The front generator bearing is installed.

If a special puller is not available, then a large open-end wrench will be required. We pick up the rear bearing with a wrench, as shown in the photo.
Lightly hit the key with a hammer and move it around in a circle to remove the rear bearing of the generator.
The rear bearing has been removed from the generator rotor shaft.
Installation of the rear bearing can be done using a piece of pipe of a suitable diameter (for example, a deep “19” socket). Using light blows of a hammer, press the new bearing onto the generator rotor shaft.

How to replace alternator brushes on a Priora

How to change the generator on a Priora

Attention, do not replace weak generators; the replacement part must have a power of at least 80, and preferably 115 Amps (these are found on luxury versions, but are also suitable for regular Priors). The generator itself is located under the hood next to the engine mount.

Remove the negative terminal and belt from the battery.
Disconnect the wires leading to the battery (there should be three, start with the one that leads to the terminal-shaped terminal - D+).
After that, you can remove the rubberized cover covering it, then use a wrench to unscrew the nut.
Manually unhook the wires leading to it from the contact pin.
Now you can disconnect the generator itself from the bracket. Unscrew the fastening from below with a key. The nut is removed together with the spacer sleeve.
After this, remove the bolt for fastening along the bottom, now it can be completely unscrewed from the bolt fastenings.
Now you can remove the tension bar and finally remove the generator itself.
The new generator is installed in exactly the same reverse order.
Don't forget to adjust the belt tension and then tighten the tension bar nut.

During this repair, it may become clear that the belt also needs to be replaced if it is discovered during the process that it has stretched too much. You can also find out about this by indirect signs. For example, the belt starts to whistle when the high beam headlights or the interior or rear window heating are turned on. With increased load on the generator, the belt may begin to slip, causing it to squeak and whistle; the only way to fix this is to replace the part.

How to change the alternator belt on a Priora without additional add-ons

You will need a minimum set of tools - two keys for ten and for thirteen.

Disconnect the negative terminal from the battery.
Loosen the fastening nut from the bottom a little (key 13).
Loosen the nut on the top of the tensioner.
Using a ten key, unscrew the tension bolt, then move the generator itself closer to the engine.
Now the supply belt is loosened enough that it can be removed and put back in its original place without being worn out. To tighten it properly, work in reverse order as described.

Website for cars and repairs.

Recently, the European repair standard has been increasingly used at car service stations. That is, most often the entire assembly is not replaced without attempts at minor repairs. But there are some operations that continue to be carried out even now. One of them is replacing the generator brush mechanism. And “Priora” is no exception here.

BRUSH MECHANISM WITH RELAY REGULATOR

On older models of generators, the brushes that transmit current to the rotor winding to create an electromagnetic field that generates electricity could be replaced individually. They were installed in a special device - a brush mechanism, from where they could be easily removed. In modern generators, brushes are mounted complete with an electronic device - a relay regulator. The relay regulator is designed to equalize the voltage supplied to the vehicle's electrical system. A transistor with a threshold for turning off the excitation voltage is built into the relay circuit. He is able to change it depending on the engine speed and, accordingly, the generator. The fact is that without a regulator, as the speed increases, the voltage jumps to 16-18 V, which can lead to failure:

side lighting lamps;
low and high beam;
instrument lighting;
electric motors of various components.

At low speeds, the generator, on the contrary, produces a low voltage of 11.5-12 V. This leads to insufficient battery charge and premature failure.

By changing the current in the rotor windings, the relay-regulator maintains the voltage parameters supplied to the on-board network within the required limits, from 13.6 to 14.5 V.

RELAY REGULATOR MALFUNCTIONS

Most often, the malfunction of the brush mechanism with a built-in regulator is the failure of the semiconductor transistor, a break or a short circuit to the housing. It is also possible for the graphite brushes themselves to wear out or break. This is characterized by a drop or complete disappearance of the charge current. On the Priora this can be seen not only by the battery indicator lamp, but also on the mini display of the instrument panel. It has a charging voltage monitoring function.

The brush mechanism of the generator on the Priora cannot be repaired. In case of any breakdown, you only need to replace the brush assembly.

HOW TO REPLACE THE BRUSHES ON A PRIORA GENERATOR WITHOUT REMOVING IT

All dynamos installed on Russian Priors are convenient in that the brush mechanism can be replaced without removing the unit itself from the car. This is not a very complicated operation, accessible to almost any car owner who knows how to hold tools in his hands. The replacement is carried out in several stages.

Battery disconnection.
Removing the power wire with a 10mm wrench from the generator.
Disconnecting the test lamp input from the connector.
Removing the rear plastic cover with snaps.
Using a screwdriver or wrench, unscrew the 2 bolts or nuts securing the brushes.
Replace the brush mechanism with a new one, connecting the wires.
Reassemble in reverse order.

After replacing the generator brushes, be sure to measure the flow of charging current to the battery with a voltmeter and compare it with the readings on the Priora instrument panel. We need to make sure that its work is objective.

Tools for work

Before you begin replacing worn elements, you should prepare the necessary tools:

wrench size 13, it is best to use an open-end wrench;
a screwdriver; a flat tool is better suited for this task;
a car head with a so-called size 10 wrench.

Step-by-step replacement of generator brushes

You can replace worn brushes without removing the generator from your car. However, according to experts, this process will be much simpler if you remove the generator from its permanent place before replacing it. After the generator is removed, the replacement process is performed in the following order:

using a screwdriver, remove the cover made of plastic to protect the generator in order to be able to get to the brushes;
the connecting plug with wires is disconnected from the brushes;
two fixing fasteners, which are located at the edges of the elements being inspected, are carefully unscrewed;
using a size 13 wrench, unscrew the fixing bolt in the center of the element;
after all the fasteners have been unscrewed, the brushes should be removed to inspect their external condition and replace them.

What signs will indicate that the generator brushes are faulty?

The following external signs will help you understand that the generator brushes have become unusable on a Priora with power steering or air conditioning:

length of the element being inspected;
if upon inspection it is discovered that the length of the brushes is less than 5 mm, they must be replaced;
Replacement will also be required if the appearance of the brushes indicates uneven wear, that is, one element is heavily worn out, and the second is brand new. Uneven wear of these elements will certainly negatively affect the operation of the generator, so experts recommend replacing them without fail.

The cost of new components for the Priora does not exceed 150 rubles; of course, you can also find cheaper brushes for the generator, but it is unlikely that such elements will serve faithfully for a long period of time, and such savings will lead to a repeated procedure for replacing these components.

Once high-quality brushes have been purchased (it is advisable to give your choice to well-known manufacturers), you can begin assembling the entire element and installing the generator in its original place.
But as was said earlier, such a process can be carried out without removing it, which, of course, must be decided by each car owner independently. These operations, as many understand, are performed in reverse order, and after the final stage it is necessary to check whether the entire generator is working efficiently. If the replacement of worn brushes is carried out correctly, and the problem with charging the battery was precisely the wear of these components, then the car owner will solve this issue, and without the help of service station employees, which will save a lot of his own money. The replacement process itself is quite simple, but if difficulties arise during the work, you can watch the training video on the Internet resource at any time, which is provided by professionals, choosing the most suitable time for viewing.

Removing a generator on a Lada car without air conditioning

Before starting work, disconnect the negative terminal from the battery and the engine protection. Prepare the keys “10, 12, 13”.

On 16 valve engines (VAZ-21126, VAZ-21127) an alternator belt tensioner is used:

Unscrew the tensioner nut (No. 2) 3-4 turns.
Loosen the generator belt by rotating the tension roller screw (No. 3).
remove the alternator belt

For all trim levels:

remove the protective cap (No. 1), unscrew the nut and remove the wiring harness terminal.
disconnect the block with wires (No. 7) from the generator.
Unscrew the nut (No. 3) and remove the bolt from the upper mounting of the generator.
Unscrew the nut (No. 5) and remove the lower fastening bolt.
remove the belt from the pulley, and then the generator itself.

ps To remove the back cover of the generator, lift three latches at the same time. This is difficult to do, so it is suggested that before dismantling the cover, fix all the clamps in the upper position by placing nails under them. Now the generator cover can be removed without difficulty.

Dear customers, in order to avoid errors when sending the voltage regulator relay 2170-3701010-13 RRG, in the “Comment” line indicate the article number, voltage and current of the generator, brand, model of your car, year of manufacture.

Generators on VAZ cars are designed to convert the mechanical energy of rotation of the crankshaft of a car engine into electrical energy. A car generator is used to charge the car battery, as well as to power the ignition system, headlights and side lights, on-board computer, audio system, ventilation and heating systems and other regular electrical consumers.

All electrical problems with the generator must be solved by checking both other elements of the circuit (in particular the battery), and its parts itself and the output voltage. One of the common problems that car owners have to deal with is overcharging. Checking and replacing the voltage regulator or diode bridge will help eliminate the first malfunction.

Voltage regulator (relay-regulator) – electrical energy converters that allow you to obtain a specified voltage at the output; They are electronic units made up of several components.

Voltage regulator 2170-3701010-13 RRG maintains the voltage of the on-board network of the VAZ-1117, VAZ - 1118, VAZ - 1119 "Kalina", VAZ 2170, VAZ -2171, VAZ -2172, LADA GRANTA within specified limits, regardless of engine speed and electrical load, due to changes in current strength (magnetic flux) in the generator rotor winding. The voltage regulator is a non-separable unit; if it fails, it is replaced assembled with the brush holder.

Multifunctional voltage regulator 2170-3701010-13 RRG is designed to maintain the voltage of the on-board network of the VAZ-1117, VAZ - 1118, VAZ - 1119 Kalina, VAZ 2170, VAZ -2171, VAZ -2172, LADA GRANTA within specified limits in all modes operation of the electrical equipment system when the generator rotor speed, electrical load, and ambient temperature change.

This voltage regulator is used in conjunction with rectifier limiting units without additional diodes as part of generators.

The voltage regulator 2170-3701010-13 RRG ensures complete disconnection of the generator excitation winding from the on-board network, which increases the reliability and safety of the power supply system.

Voltage control and regulation are carried out directly at the output terminal of the generator - all power supply circuits for modern high-class foreign cars are built on this principle. Control of the generator start-up, as well as control of its rotation speed, is carried out directly on one of the output power windings.

Regulator 2170-3701010-13 RRG is installed directly on the BOSCH F000BL0652 / F000BL06F8/ F000BL0707 generator, 14V, 110A in VAZ-1117, VAZ - 1118, VAZ - 1119 Kalina, VAZ 2170, VAZ -2171, VAZ -2172, LADA GRANTA.

The rotor and stator are components of an electrical machine (in this case, a generator), where the fixed part is called the stator, the moving part is called the rotor. The stator and rotor are separated by an air gap. Their active parts are windings and magnetic circuit; all other parts are structural, providing the necessary strength, rigidity, cooling, rotation, etc.

Brush assembly - provides electrical connection of the rotor circuit with circuits located in the stationary part of the machine; consists of two sliding contacts.

F000BL10S2 BOSCH rectifier block (diode bridge) – designed to convert (“rectify”) alternating current into pulsating current; They are a structure of several diodes.

When the ignition is turned on, voltage is supplied to the excitation winding of the generator (terminals “L” of the generator and “+” of the regulator) through a circuit that includes an indicator in the instrument cluster (the indicator lights up). After starting the engine, the excitation winding is powered by the diodes of the rectifier unit (the alarm goes off). If the indicator lights up after starting the engine, this indicates a malfunction of the generator or its circuits.

It is not recommended to disconnect the battery while the engine is running. The resulting voltage surges in the on-board network can damage the electronic components of the car.

The “minus” of the battery should always be connected to the “ground” of the car, and the “plus” to the “B+” terminal of the generator. Reverse connection will lead to breakdown of the generator rectifier diodes.

To make sure that the voltage regulator is working properly, turn off all consumers except the high beam headlights and measure the voltage at the battery terminals.

If the voltmeter readings first increase and then decrease as the engine speed increases, the cause of this is loose tension or slipping of the generator drive belt.

Generator 2170–3701010 with a return current of up to 115 A and Generator 1119–3701010 with a return current of up to 85 A (engine 11194) are not interchangeable , the mounting points are located in different places. In this case, in adjusting the belt tension on 11194, an additional roller assembled with a bracket is used.

On engines 21116 and 21126 there is no such roller; the belt tension is adjusted by shifting the generator itself and checked with a frequency meter.

To protect the on-board network from voltage surges during operation of the ignition system and reduce interference with radio reception, a capacitor with a capacity of 2.2 μF (±20%) is connected between the terminals of the “positive” and “negative” valves (between the “+” and “ground” of the generator) on the rectifier block. When the ignition is turned on, voltage is supplied to the generator excitation winding through a control lamp in the instrument cluster (the lamp is lit).

After starting the engine, the excitation winding is powered by additional diodes of the rectifier unit (the control lamp goes out).

If the lamp lights up after starting the engine, this indicates a malfunction of the generator or its circuits.

Checking the condition and adjusting the tension of the generator drive belt

The demonstration works using the example of a car without auxiliary units (air conditioning compressor or power steering pump).

To complete the work, you will need an inspection ditch or overpass.

1. We prepare the car for work.

2. Remove the engine splash guard and visually check the condition of the generator drive belt.

Replace any belt that has cracks or other damage.

3. We press the generator drive belt with a force of 98 N (10 kgf) exactly in the middle between the generator pulley and the engine crankshaft pulley.

If it is difficult to estimate the force created by the hand, you can use a household steelyard with a maximum permissible load of 10 kg. A correctly adjusted belt should bend by 6-8 mm. Continue reading →

Replacing generator brushes on VAZ 2110, VAZ 2111, VAZ 2112

Brushes are an integral part of the generator. They are inexpensive and can be replaced in literally 20-30 minutes. Thanks to the brushes, the battery is charged, and current from the generator is supplied to the on-board network. Failure is fraught with consequences: the car does not drive, the battery charge lamp immediately lights up, signaling that the generator is not working properly and requires inspection. Do not operate a car with a glowing light on the dashboard, because the battery will suddenly run out in the wrong place, the car will stall and you are unlikely to start the car (current stops flowing to the ignition system, and therefore the spark disappears and the fuel-air mixture stops igniting).

Note! You will need the following tools: wrenches, sockets with a wrench, new brushes and screwdrivers.

Location of brushes

They are located under the generator cover (indicated by a red arrow). Remove it and unscrew the screws securing the voltage regulator (the regulator is indicated by a blue arrow). It comes complete with brushes, the screws do not attach the brushes directly, but the regulator, the brushes are inserted into it.

Generator Lada Priora

The main function of the generator is to provide continuous power to all electrical equipment while driving. The failure of a node will lead to the failure of the entire system, so its condition should be monitored especially carefully.

Let's consider the main characteristics of the factory generator installed on the Lada Priora car, as well as similar models.

Selection of components

The original generator, installed on a car with a 16-valve engine at the factory, is marked with article number 5102.377. Its cost, as a rule, fluctuates around six to seven thousand.

Carefully check the generator itself and its packaging before purchasing so as not to encounter a counterfeit. It is important that the part is free of unevenness, chips and paint runs, as well as extraneous markings.

To avoid overpayments, you can purchase a similar original spare part. The following devices are suitable for installation on Lada Priora:

VAZ (power 120/115a);
KZATE (115a);
BATE (90a);
BOSCH (120a).

What signs will indicate that the generator brushes are faulty?

The following external signs will help you understand that the generator brushes have become unusable on a Priora with power steering or air conditioning:

length of the element being inspected;
if upon inspection it is discovered that the length of the brushes is less than 5 mm, they must be replaced;
Replacement will also be required if the appearance of the brushes indicates uneven wear, that is, one element is heavily worn out, and the second is brand new. Uneven wear of these elements will certainly negatively affect the operation of the generator, so experts recommend replacing them without fail.

The cost of new components for the Priora does not exceed 150 rubles; of course, you can also find cheaper brushes for the generator, but it is unlikely that such elements will serve faithfully for a long period of time, and such savings will lead to a repeated procedure for replacing these components.

Generator replacement process

Most often, the unit fails precisely after connecting various electronic devices to the onboard part of the car. The more energy consumers there are, the higher the generator voltage should be.

This is why we recommend that you consider the number of electronic devices you use when purchasing a new node. The best option is generators with 115-120 amperes.

Let's get started with the work. To dismantle the generator you need a 13 key:

Disconnect the battery. Remove the mechanism drive belt according to the operating instructions.
Disconnect the connector from connector D. Then move away the rubber boot to gain access to the fastening of the contact pin and the wiring block.
Now unscrew the fixing nut and remove it. Remove the screw and get rid of the remaining fasteners. Don't forget about the adjusting screw.
When all fasteners are removed, dismantle the tension bar.
Remove the mechanism itself.

Now you can replace individual elements or purchase a new unit. After completing the repair work, all that remains is to install the generator in place; the process itself is almost identical (performed in reverse order).

Please note that if you are the owner of a Lada Priora with air conditioning, the process of removing the generator will be slightly different:

Remove the protection and disconnect the positive terminal from the generator.
Lower the belt tensioner roller and unscrew the air conditioner fasteners.
Move the air conditioner away to make room for further removal of the generator.
After unscrewing all the fasteners, carefully remove the device.

Don't forget to adjust the strap tension to avoid malfunctions of the mechanism. Then tighten the tension film fixing nut, maintaining a torque of 20 Nm. Be sure to rely on the diagrams during installation to avoid mistakes that will lead to system failure.

You may need additional replacement of bearings and diode bridge. If you have doubts and are not sure that you can carry out the procedure for replacing components yourself, it is better to contact a salon.
