VAZ 2101 fuse box: location, photo, diagram, which one is responsible for what

Some tips on VAZ 2106 fuses

Cleanliness of landing nests. I think everything is clear here, the cleaner the fuse socket, the less resistance in this circuit and, as a result, less heating. If the contacts are dirty, the fuse heats up and melts, a short-term loss of contact is possible, which is quite dangerous, for example in the case of light. Compliance of fuse ratings with the manufacturer’s recommendations

It is also quite important not only to keep the contact groups clean, but also to use fuses of the ratings recommended by the manufacturer. Ignoring these requirements threatens the failure of electrical equipment in the network or, even worse, a fire. Under no circumstances should you replace a fuse in a VAZ 2106 or another car with a so-called “bug”, coin, screw or other thing

I think you yourself understand that a fire is not far away here. The fuse has tripped. This is a fairly common situation and there is no need for hasty decisions; first you need to find out which circuit this fuse protects (below is a list of protected circuits and fuse numbers for the VAZ 2106, I hope there will be one for other models soon). Then try to remember, understand what could have caused the short circuit; it is highly not recommended to insert a new fuse in place of the blown fuse if the cause of the blown fuse has not been eliminated. If you find the cause, then eliminate it, insulate the wires, insert a new fuse. Fuses are blowing. If the conductive section melts, then this is understandable, most likely a short circuit. But if a plastic insert melts, then this is a signal of poor contact in the socket or an overload of the circuit protected by this fusible insert. Additional consumers have their own fuse! You should not connect many third-party consumers (radio, heating, etc.) to one fuse!

Types of fuses used in the VAZ 2106

VAZ 2106 fuses have found practical application, photos of which are presented on our Internet resource. If we talk about their cost, the price varies greatly due to the difference in the materials used to make them. In any case, the cost of a set of fuses of various types does not exceed 200-250 rubles.

The “classic” of this modification in the first years of production is equipped with an obsolete type of fuse panel, where plastic fuses with a conductive lining made of zinc alloy are installed, the reliability of which is low. With increased load, the fuse block is subject to increased heating, which can lead to melting of the elements. This, on the one hand, creates the preconditions for a vehicle fire, and on the other, opens the existing electrical circuits.

To improve this situation, it is necessary to modernize the old safety elements and install Euro models, which will be mounted on the basis of the fuse block from the Volga GAZ 31110. The main advantage is that blade fuses are used on the VAZ 2106 with more reliable fasteners. Their advantages include smaller dimensions and increased thermal stability, which eliminates heating of the system unit.

In addition, contact becomes significantly better. When installing fuses of a new type, it is necessary to enter updated fuse designations, marking the colored wires at the places of their previous attachment. They will also differ in face value. So, in a VAZ 2106, the high beam fuse requires the installation of a safety device with a current of 15 A, and the fuse for the signal has a current rating of 10 A. If the fuses burn in the VAZ 2106, then modernization is necessary, and it also includes the installation of jumpers between the safety devices.

The connection of such bridging elements must be carried out in a manner analogous to the connection of the device block from the VAZ 2101, and the elements themselves must be provided with insulating protection. To connect the flag fuses correctly, the diagram should look like this:

Then the energy supply system will be reliably protected from short circuit mode. Thus, the true purpose of the VAZ 2106 fuses will correspond to the protective properties of the vehicle’s energy supply system.

Solutions

First of all, you need to check the backlight bulb; if it does not work, it needs to be replaced. Also, the reason that the instrument panel does not light up in the VAZ 2114 may be a violation of the integrity of the wiring. She should be called. A damaged fuse and electrical circuit, as a rule, cannot be repaired - they simply need to be replaced. Let's look at quick ways to solve these problems.

One or more light bulbs do not light up

One of the most common reasons why the instrument panel lighting on a VAZ 2114 stopped working is burnt out light bulbs. The electrical circuit in this model is designed in such a way that if one light source fails, all of them stop working. To determine exactly what is broken, you will need to ring the entire system using a tester. Another reason for the lack of lighting may be the independent installation of LEDs instead of standard incandescent lamps. In this case, an error is often made in the distribution of power or the electrical parameters of the led elements are calculated incorrectly.

Wiring

Damage and rupture of wires in the power supply system of the on-board network is not uncommon on a VAZ 2114 car. To locate the disconnection point, it is necessary to test all possible wires that can be found surrounded by the instrument panel illumination. In addition, the light bulbs may not light due to the formation of oxide deposits on the pads. To fix the problem, you will have to dismantle it and clean the entire contact group.

Fuse

Before you start calling the electrician of the VAZ 2114, the fuse box must be dismantled. Otherwise, the diagnostics will not be complete and will not reveal a complete picture of faults in the instrument panel lighting system. The cause of breakdowns should be sought both inside the electrical wiring distribution system and outside - in the seat. If during testing it is determined that the module is faulty, it should be replaced with a new one, since such equipment simply cannot be repaired.

The board is damaged

A violation in the electrical circuit of the dashboard system board on the VAZ 2114 is the most serious problem of the above. Despite the fact that many radio enthusiasts still repair and eliminate this defect, in practice it is better to immediately replace it with a new one. The main reason that the backlight does not light in this case is a previous short circuit in the circuit. External signs of this will be as follows:

If the light source is an incandescent light bulb, the wiring connection to the board will be black.
If LED elements are installed, a darkened junction between them and the base will indicate the destruction of the microcircuit.

Important! After removing the panel, it is necessary to ensure that the surrounding area is as clean as possible to prevent moisture, dust and debris from entering the electrical circuit.

Purpose of the fuse box

Fuse box VAZ 2101

The fuse box is the most important unit in the electrical circuit of a car, which combines all the safety connectors. Its main purpose is to create convenient conditions for the driver to replace blown fuses. Agree, if the fuses are not in one place, but are located throughout the machine, this will create a certain difficulty when checking them. Let's consider a separate situation. Let's say a car engine does not start for some reason unknown to us. In this case, the first thing to do is check the condition of the fuses. By opening the unit cover, we can quickly locate the blown fuse and replace it. This is how the engineering thought that created this node helps us get out of such non-standard situations in the shortest possible time. By the way, this is not the only option when checking the fuse box allows you to quickly solve the problem. To conclude this section, we add that the block consists of the following parts:

Plastic body of the block.
Fuse holders are fixed in the housing.
Plastic housing cover.

The fuse box is located in the car interior, on the driver's side under the panel.

Recommendation: It is strongly recommended to protect the unit from mechanical damage. Fuses should always be covered with a cover to avoid shorting the electrical circuit.

Features of the VAZ-2101 electrical circuit

For the VAZ-2101 there is also a standard electrical diagram compiled by specialists from the manufacturer of this car. Its main features are as follows:

The DC electrical circuit is single-wire.
The direct current connection is carried out from the “ground” to the “minus” terminal of the current source (on the VAZ-2101 such a conductive line “ground - minus” is the entire body, that is, all devices that consume electricity are connected by one wire to the “ground”-body) .
The DC source is a battery with the following characteristics:
voltage – 12 V.
Alternator with the following characteristics:
power – 500 W;
the presence of selenium rectifiers (they are built into the back cover of this device);
rated current – 42 A;
maximum current at permissible load – 53 A (at 5,000 rpm);
voltage – 14.5 V.
Voltage regulator with the following characteristics:
automatic adjustment (two-stage type).
Battery with the following characteristics:
discharge mode – 20 hours.

All of the listed elements are connected to the VAZ-2101 using a parallel type.
For the VAZ-2101, a circuit of fuses has also been developed, which are needed to prevent a short circuit in the electrical circuit in a certain closed section (it is this that is sketched on the electrical circuit). For convenience and quick search for a failed fuse, the entire graphic diagram is divided into ten parts. This is exactly the number of fuses used on the VAZ-2101. They are also marked in different colors and numbered according to the actual data.

If one of the elements of the vehicle's electrical wiring is in poor condition, it will require immediate replacement. In this case, you cannot do without knowledge of the electrical circuit.

Features of the electrical wiring of the VAZ 2110

As you know, when you turn the ignition key, the main current consumers are activated, however, it must be taken into account that the power supply wiring is in constant “combat readiness”:

Headlight high beam control unit;
Brake lights (when you press the pedal, naturally);
Parking lights;
Lighting of instruments and vehicle interior;
Sound signal.

Attention! If the engine temperature is high, even with the ignition off, the cooling system fan will run until the thermal relay commands to turn off. This function prevents the car engine from overheating.

Most of the electrical wiring in the VAZ 2110 is protected from short circuits by fuses, however, it must be taken into account that the following are unprotected:

Wire connecting the charging relay and the battery;
Wiring responsible for starting the engine and operating the ignition system;
Wiring of the generator itself (with the exception of the excitation winding, which is activated after starting the engine and simply after turning the key in the ignition).

Attention! Working with the above should be carried out with extreme caution, and this applies not only to the car wiring itself - when a short circuit occurs, printed circuit boards, namely their conductive paths, often burn out.

Wiring harness in the cabin

The front wiring harness, located in the engine compartment, is the main electrical system. The front beam enters the car interior through a technological hole with a seal under the instrument panel. The front end electrical system connects to the dash wires, fuse box, switches, and ignition. In this part of the cabin, the main electrical circuits are protected by fuses.

The new cable will provide sufficient voltage to power current consumers in the cabin

The fuse box is located to the left of the steering wheel. Auxiliary relays are attached to the bracket behind the block. The reliable operation of the VAZ 2101 depends on the proper functioning of electrical devices and relays. Fuses protect the electrical circuits of the VAZ 2101 from short circuits.

Simple fuses are a reliable safety element in the event of a short circuit

List of electrical components protected by fuses:

Horn, brake lights, interior lamps, cigarette lighter, portable lamp socket (16 A).
Heating motor, wiper relay, windshield washer motor (8 A).
Main beam of the left headlight, high beam indicator lamp (8 A).
High beam of the right headlight (8 A).
Low beam left headlight (8 A).
Low beam of the right headlight (8 A).
Side light of the left sidelight, side light of the right rear light, size indicator lamp, instrument panel light, license plate light, trunk light (8 A).
Side light of the right side light, side light of the left rear light, cigarette lighter lamp, engine compartment light (8 A).
Coolant temperature sensor, fuel level sensor and reserve indicator lamp, oil pressure lamp, parking brake lamp and brake fluid level indicator, battery charge level lamp, direction indicators and their indicator lamp, reversing lamp, glove compartment lamp ) (8 A).
Generator (excitation winding), voltage regulator (8 A).

Switching of instruments in the cabin is made with low-voltage wires with elastic oil- and gasoline-resistant insulation. To facilitate troubleshooting, the wire insulation is made in different colors. For greater distinction, spiral and longitudinal strips are applied to the insulation surface to eliminate the presence of two wires of the same color in the bundles.

On the steering column there are contacts for switches for the direction indicator, low and high beam, and sound signal. In the assembly shop, the contacts of these switches are lubricated with a special conductive grease, which must not be removed during repairs. Lubrication reduces friction and prevents oxidation of contacts and possible sparking.

The intermittent signal of the turn signals is determined by the breaker relay. The ground connection is provided by black wires, the positive connection is provided by pink or orange wires. Inside the car, the wires are connected:

instrument panel and indicator lights;
headlight clusters;
direction indicators;
interior lighting;
wiper;
foot-operated windshield washer.

The rear wiring harness runs along the left side of the cabin under the floor mats. A thread runs from it to the light switch in the door pillar and the parking brake lamp switch. The branch to the right lamp runs behind the rear beam along the floor of the body, where the wires connecting the level indicator and fuel reserve sensor are located. The wires in the bundle are secured to the floor with adhesive tape.

How to properly replace a burnt out element

Removing the fuse box

You need to pull the fuses out of the corresponding sockets using special plastic tweezers, which can be found here, in the upper right corner of the VAZ 2114 mounting block. You cannot pry fuses on non-energized circuits with any metal objects due to the risk of a short circuit. It should be taken into account that the electrical circuits of the sound signal, alarm, etc. are always energized. To ensure safety when repairing the circuits, the circuit must be de-energized - you just need to disconnect the wire from the “negative” terminal.

It is not always possible to visually accurately determine the performance of fuses. It will be possible to make a clear decision only after the “ringing”. To do this, you will need a regular tester, which will need to be set in advance to the “dialing” mode. After this, it will be enough to simply attach two terminals of the tester to the terminals of the suspicious fuses. If a characteristic sound is heard, the fuse is good - the cause of the malfunction of the car’s equipment is not in it, but probably somewhere further in the wiring or in the device itself.

Lastly, never use copper “inserts” or fuses that are not rated for amperage. Using an inadequate replacement designed for a higher current, there is a risk of damage to the “track” of the unit’s printed circuit board and even failure of the electrical appliance. Insufficiently powerful fuses will not be able to ensure long-term and uninterrupted operation of the current consumer in the vehicle's electrical network.

You can drive a car comfortably and safely only by clearly monitoring its basic parameters. However, on a VAZ 2114 it sometimes happens that the instrument panel lights turn off or do not light up at all. There can be many reasons for this. Let's consider why such a malfunction occurs, what are the ways to solve it, and what are the main stages of the procedure for eliminating it.

General principles of operation of electrical equipment on vehicles of the VAZ-2110 family

Basic principles of electrical wiring on a VAZ 2110 with carburetor and injection engines:

All electrical equipment and devices powered by voltage are based on a single-wire connection. When developing the on-board network diagram, VAZ concern specialists thought out that electrical circuits of a certain color would be responsible for specific options. Therefore, certain devices are connected through power lines of certain colors. Thanks to this, the owner of the car can figure out the electrical circuit himself, which will allow him to carry out repairs on his own.
The negative contact of any electrical appliance on the VAZ 2110 is ground. It connects to the vehicle body.
The positive contact from the battery on a VAZ is always red. Therefore, when performing repairs, it is not recommended to change the color of the electrical circuit.
Each electrical system connected to the on-board network has a separate harness with electrical circuits.
“Ten” is designed in such a way that when the battery is activated, voltage is supplied to all electrical appliances and equipment. Therefore, when performing electrical wiring repairs from the battery, it is necessary to disconnect the negative terminal.
Some VAZ 2110 cars are equipped with. This type of system began to be used to provide a higher quality spark compared to the contact version. A good spark is needed to ensure efficient combustion of the combustible mixture. For high-quality operation of the contactless ignition system, it is required.

Relay under the hood

Several relay elements are located in the engine compartment.

The turn signal and hazard warning relay (RS-491) is located on the bulkhead under the instrument cluster.

Headlight and battery charge relay

Scheme

Purpose

Battery charge indicator relay (PC-702)
Headlight high beam relay (VAZ-21011 and BA3-21013)
Relay for low beam headlights (VAZ-21011 and BA3-21013)

1) Relay RS-702 is used to turn on the warning lamp on the instrument panel when the generator voltage is insufficient to charge the battery. 2) Headlights. On cars 2101 and 2102, as well as on 21011 produced before 1980, the headlights are turned on by a switch located on the steering column when the exterior lighting switch is on. On cars 21011 produced since 1980 and on cars 21013, the headlights are turned on by the same switches, but through auxiliary relays.

Still have questions? Ask them in the comments.

Purpose of the turn relay

The Traffic Rules in force in Russia clearly state that when making maneuvers, it is necessary to turn on the direction indicators, and in their absence, indicate the direction of movement with your hand. However, now most cars and motorcycles are equipped with turn signals, so you rarely need to use your hands to indicate the direction of travel.

When turned on, the direction indicators flash, that is, they light up and go out at certain intervals, so they attract the attention of other road users, and it is quite difficult not to notice the turn signal being turned on. The blinking of direction indicators also plays another role - it does not allow drivers to confuse their activation with the activation of brake lights or the inclusion of side lights

Periodic turning on and off (that is, the same blinking) of the direction indicator lamps is realized using a simple device that is part of the vehicle's electrical system - a turn relay, which is often simply called a breaker or breaker relay.

The breaker relay included in the turn signal circuit performs three functions at once:

Supplying electric current to the direction indicator lamps (that is, turning on the “turn signals”);
Ensuring intermittent operation of the direction indicator lamps (their blinking);
Creation of characteristic clicks, signaling to the driver of the car that the direction indicators are working.

In cars of the Volzhsky Automobile Plant of various generations and models, several types of turn relays are used, which have different operating principles and characteristics.

Removal and Replacement Guide

Before you begin replacing the safety devices located in the main unit, you must turn off the ignition and battery terminals under the hood.

The replacement procedure is carried out as follows:

Find the installation location of the device. There are latches on the plastic cover of the block; press them. After removing the cover, you will be able to see a diagram printed on the reverse side, which indicates the location and purpose of all used elements.
Then you need to identify which device has failed and needs to be replaced. Sometimes a breakdown can be determined visually - the component itself may be burnt out, sometimes a broken thread is clearly visible in it.
Under the cover of the device you will see tweezers, which can be used to remove the device. If you don't have tweezers, you can use pliers.
Remove the burnt out element and replace it with a new one, then replace the cover and connect the battery terminals (video filmed and published by the AVTOCLUB_22 channel).

To check and replace, follow these steps:

First you will need a Phillips screwdriver, use it to remove the two switches located in the middle of the console, near the audio system.
Using a screwdriver, you will need to press out two fasteners.
Then remove the plastic insert.
You can now remove the fuse housing. Remove the protective cover of the device and replace the part with a new one.

Removing and replacing the block with components is done as follows:

First, open the engine compartment of your car and remove the air filter housing. Unscrew the nuts that secure the housing using a Phillips screwdriver.
Then under the device you will be able to see a plug with cables connected to the device, you need to unplug it. The product body itself is marked in colors; it corresponds to the color of the connected connectors. By taking these plugs into account, the need to label cables can be avoided.
After this, you should climb into the vehicle interior and remove the shelf, which is located under the control panel. After this, unscrew the bolts that hold the glove box housing.
Next, disconnect the plug with cables connected to the connectors directly on the device. Once you do this, you will be able to see the color coding.
Using a wrench, remove the bolts that secure the block itself. Please note that the outermost screw on the case is hidden, so you will not be able to see it immediately.
At the end, remove the block with the devices, now the device can be replaced. Installation of a new device, as well as assembly of components, is carried out in the reverse order.

What else is this fuse responsible for?

Fuse element F10 is responsible for keeping the instrument lights on. In addition, it ensures the operation of the side lights on the left side of the car, the license plate light, the cigarette lighter, the ashtray and the heater adjustment.

If the instrument backlight fuse on a VAZ 2114 blows, the left side lights, license plate lights, ashtrays and other above-mentioned elements should also not work. To diagnose a malfunction, you need to find this fuse in the mounting block and inspect it. Often the defect is clearly visible externally.

You can also check it with a multimeter. If there is voltage at one end of the part, but not at the other, it has failed. Replacing an element with a known good one also helps diagnose a breakdown. If everything works after this, the reason has been established correctly. The fusible element is cheap. Therefore, you should look for the cause of the breakdown by replacing it. This usually helps solve the problem. If this does not help, you need to consider other faults.

The jumpers were made at home. Particles of molten metal freely penetrate into the environment, increasing the likelihood of fire in surrounding surfaces. F2, response current 8 A, allows you to protect the circuits of the windshield wiper and its relay, the electric washer motor and the heater.

This feature allows the existence of the following types of fuses, among which are popular: Open. Rear lights brake lamps.

First of all, you need to purchase LEDs, resistors, if it is difficult for you to calculate the value yourself, then you can ask the seller, heat shrink. The rest was all there: Time to create 2 days and then during the working day, without rushing: In the evening I will install it in the car!

Still, we couldn’t do without a pair of “spacer” nuts: - : 8. Relay for switching on headlight cleaners and washers K3.

Replacement is very easy and quick: Unscrew the nuts that secure the block and pull it out. More powerful fuses are usually installed under heating household appliances, washing machines, and refrigerators.

The breaker responsible for the operation of the direction indicators is located on the partition in the engine compartment opposite the dashboard. Most experts advise not to power a large number of different-sized electrical outlets, lamps, sockets, and household appliances using one fuse. LADA NIVA. Transition to a Euro fuse block.

Other reasons for backlight failure

Sometimes the instrument panel stops lighting for other reasons. The most common of them are the following:

Burnt out light bulbs or LEDs. To determine the failure of the lamps, you need to remove the device, but this will not be easy. Faulty lighting fixtures, like fuses, cannot be repaired. They need to be replaced. If the light bulbs burn out frequently, it is advisable to check the car wiring with a multimeter within a reasonable time or contact an auto electrician. Often the reason for this is unqualified replacement of conventional lamps with LEDs;
Burnt out dashboard contact board. Due to excessive wear or frequent voltage fluctuations in the on-board network, it may fail. The part consists of microcircuits. It is almost impossible to diagnose and repair it at home. Therefore it will have to be changed. The fee costs about 400-600 rubles. To replace it, you will have to disassemble the dashboard;
Broken wiring . Damage may occur in one or more places. To identify the defective area, you need to test all the wires with a multimeter. Sometimes this takes several hours. Without a good knowledge of electrical circuits and auto electricians, it is often difficult to determine this malfunction. Sometimes the dashboard may not light up due to oxidized or dirty contacts. Cleaning the contact connections will help restore the functionality of the part. In rare cases, the problem is caused by other faults.

Operating a car with a non-lit instrument is not prohibited by law. But driving with such a breakdown is inconvenient and uncomfortable, since in the dark the instrument readings are not visible, and there is no information about the condition of the car. Therefore, such driving is risky. In addition, this may be accompanied by other, more serious malfunctions. They often prohibit the use of the car. Therefore, it is recommended to diagnose and fix the problem within a reasonable time. Luckily, you can usually do this yourself. And only a wiring break requires the intervention of an electrician.

The price of a new VAZ 2101 fuse box will be about 400 rubles, which is not very expensive. Believe me, installing a new unit will solve a lot of problems associated with the electrical wiring of the penny. The procedure for replacing the old mounting block with a new one:

Disconnect the battery.
Make jumpers from female connectors, pieces of wire no more than 1.5 square meters. mm. and heat shrinkage.
Install the prepared jumpers on the new mounting block. Connect the third and fourth, fifth and sixth, seventh and eighth, ninth and tenth.
Unscrew both nuts that secure the block to the bracket.
Without disconnecting the wires, remove the old unit.
One at a time, connect the wires from the old to the new mounting block.
After connecting all the wires, carry out a visual inspection and can be tested by applying power.

In order not to check the functionality of all the mechanisms that are included in the electrical circuit of the VAZ 2101, use a 12 V light bulb or a voltmeter.

Using one of these tools, check for voltage at the output of each fuse. After this, install the plastic housing and screw it to the bracket with nuts. Close the lid and enjoy using it. Believe me, now you will look there very rarely.

In this article you will learn how to replace a standard fuse block with a Euroblock. To begin work, disconnect the battery terminal. Next, take an 8 mm wrench and unscrew the old fuse box, without pulling out the wires. Then take a piece of paper and draw a 10x3 sign.

Why is all this needed? If you immediately pull the wires out of the fuse box, then I assure you that when you connect the wires to the new block, you will get confused and connect them incorrectly. Therefore, sketch out the connection diagram in a table on paper. Then take regular paper tape and tie the wires together. Let's look at the old fuse block, and we see that contacts 3-4, 5-6, 7-8, 9-10 are bridged, and their fuses are located at the bottom. Approximately the same picture will need to be recreated on a new block. In total we will need four jumpers. This is done very simply. Each jumper consists of a small segment of the “mother” type. This kind of work can be freely done with your own hands.

The next step is to carefully connect the required fuses with jumpers, while trying not to mix anything up. After this, you need to connect all the wires to each other. Start with the first fuse. Be sure to follow the sequence that is sketched on your paper. Keep in mind that on the old (standard) fuse box the top two wires are connected vertically, but on the new fuse box they will be connected horizontally

Note! Before connecting all the wires, it is worth sealing the female terminal of each wire, since they are too close to each other. The new fuse box may have a short circuit.

After you have completed all the work, turn on the ground and check all circuits for functionality.

In this article, clearly, using photos, materials are provided on how to correctly replace fuses on a VAZ 2101. In addition, the article details the design features of the mounting block of this car model and provides guidelines for servicing and replacing the fuse block. The Zhiguli car has long become a cult model of the domestic automobile industry. This legendary car once won the hearts of many car enthusiasts. And, what’s most interesting, many car owners, having purchased a fairly expensive modern car model today, continue to keep their favorite “penny” and carefully look after it. However, this car still serves faithfully for many motorists. And, despite their age, these cars look great and are in excellent condition. All this thanks to timely maintenance and high-quality repairs. But to a greater extent, in this case, the driver’s attitude towards his car plays a role. Next, it is proposed to consider the features of servicing a specific unit in this car, namely the fuse box.

Parameters, checking and replacing fuses

Purpose

The main purpose of fuses is to protect the electrical circuit from short circuits by destroying their elements when the specified current value is exceeded. That is, when a short circuit occurs, a current with a greater value than it is designed passes through the fuse part of the fuse, which leads to the destruction of the fuse part and a break in the electrical circuit, which ultimately saves it.

Burnt and intact fuses

Attention! Replacing fuses on a VAZ 2110 eliminates the use of metal tools, as they can lead to a short circuit in the vehicle's electrical circuit.

Options

Currently, fuses are based on several parameters:

By type - knife and flat (plug).

Knife type

Plug type

These two types have gained great popularity due to their reliability and good contact, moreover, their price is mere pennies.

Sizes: mini, maxi, medium.

By denomination and color.

Matching the color and rated current of automotive fuses

The basic current rating of automobile fuses varies from 5 to 30 Amps.

When replacing VAZ 2110 fuses with your own hands, you must comply with some requirements, namely, that the fuses have the following values:

The rated voltage was equal to or greater than the mains voltage;
The rated current was equal to or greater than the rated current of the electricity consumer;
The rated breaking current was equal to or greater than the rated current expected during a short circuit.

In addition, replacing VAZ 2110 fuses in the engine starter circuits includes checking them for the capacity of the starter inrush current, that is, they should not burn out when the engine starts.

If replacing a fuse on a VAZ 2110 took you by surprise, and you doubt what power of fuse to replace the burned one, I can offer you a simple formula for calculating the operating limit of the fuse element:

Inom = Wmax / U, where
Inom – operating current in Amperes;
Wmax – consumer load power in Watts;
U – mains voltage in Volts (in our case 12 V).

After basic calculations, replacing a fuse on a VAZ 2110 comes down to selecting one from the standard list with an operating current value exceeding the calculated value obtained.

Attention! It is prohibited to disconnect the battery and ignition switch while the engine is running, as this may result in failure of the voltage regulator and electrical components.

Examination

How do you usually check and replace fuses on a VAZ 2110 and indeed on any car? Do you remember?

Not trusting anyone, we take out each fuse in turn with our own hands and inspect it against the light, thereby checking the integrity of the fusible element. I must say that the procedure is not reliable and labor-intensive, and it simply happens that banal oxidation of the contacts has occurred.

I suggest using a simple “test” - without removing it from the socket, we turn on the required electrical circuit (heating, lighting, wipers, etc.) and check for voltage at both terminals of the fuse. If there is no voltage on one of them, this means that the fusible element has burned out.

"Prozvonka"

This check is simple and takes minimal time.

Attention! When checking the circuit for integrity, it is prohibited to short-circuit the negative wire (check for a spark) as this renders the vehicle’s electrical equipment unusable. And even short-term contact of the output of generator No. 30 with ground leads to inevitable burnout of its diode bridge.

Advice! Testing of the generator is carried out only with an ammeter or voltmeter; moreover, in order to avoid failure of the diodes in the rectifier unit, it is prohibited to check them with a megohmmeter and a “control” with a lamp with a rated voltage of more than 12 V, as well as to check electrical circuits with these devices without disconnecting the generator terminals from the network.

By the way, despite the apparent simplicity of the procedure, replacing the VAZ 2110 fuse has its own pitfalls, namely low-quality materials used in manufacturing, that is, an elementary fake.

If store-bought fuses seem to be of poor quality, perform a basic check - short circuit one of them. That is, we hook one of the terminals to “plus”, the other to “minus”, a high-quality fuse should blow out, and the fake one will melt.

Conclusion. If there is a short circuit in the car's electrical wiring, a low-quality fuse will not be able to protect the electrical circuit, which will inevitably lead to melting of the wiring itself, failure of the electricity consumer and possible fire, the same applies to homemade “beetles”.

Replacement

The largest and main part of the fuses and relays in the VAZ 2110 are located on the left side and slightly below the steering wheel. As a rule, tweezers are also located there, with the help of which a burnt fuse is replaced.

Relay description

Advice! The serviceability of the relay can only be checked by replacing a suspicious one with a known good one, while keeping in mind that the heated relays for the rear window, headlights, starter, and power windows are interchangeable.

Advice! If you lose tweezers, it is better to use pliers than your hands, since when pulling out by hand it is difficult to resist, no matter how you start to swing the fuse in the socket due to its “tight” fit, which significantly weakens the contact area.

In addition to the above, in the “top ten” there are additional relays and fuses related to the injection system. They are installed in the console, or rather behind its side trim.

Attached to the right side of the dashboard with two screws.

Additionally

Additional fuses are all rated at 15 Amps and are responsible for:

Controller (ignition module);
Sensors for heating (oxygen), air flow and vehicle speed, adsorber valve (blowing it);
Fuel pump and injectors.

Additional relays in turn control:

Cooling fan;
Gasoline pump;
Ignition (also the main relay).

Marking of additional electrical circuits

In addition, behind the mounting block itself, in the instrument niche there is a fuse that protects the electrical circuit that powers the fog lights (shown by an arrow).

Main difficulties of repair

The biggest difficulty, especially for novice car enthusiasts, is the fact that the wires in the electrical circuit and in reality can be marked with different colors.
This problem is very relevant for “old” cars that have been repeatedly repaired. Previous owners are rarely puzzled by the problem of maintaining the correct color of the cables, installing the first ones that come to hand. In this case, the new owner will have to spend time finding out what the former owner has changed. Even more difficult are situations when a wiring change has been started but not completed. In this case, it will be even more difficult to navigate. Trying to figure out where a particular guide leads can take days, and sometimes weeks. Therefore, if you purchased a car with unfinished electrics, it is better to purchase a kit and make the connection according to the specified diagram.

This solution has immediate double benefits. Firstly, you will be able to understand which cable leads to which consumers, and secondly, old electrical wiring, which may not be working, will be eliminated. New wires will serve you reliably for a certain period of time, which means you won’t have to worry about ringing the circuit a month after purchasing the car.
