Additional starter relay VAZ 2110 wiring diagram

Hi all! I’ll tell you about a very useful modification that will be useful for owners of elderly VAZ 2110. Many ten-year-olds have encountered a problem when, in hot weather, a hot engine does not respond to the movement of the key. The starter does not turn and you have to go under the hood with a screwdriver and make a direct connection to the contacts. In the case when the starter is working (in my case it is completely new), the culprit for this trouble may be the contact group of the ignition switch. Over time, the contact group in the ignition switch wears out or the current collector contacts burn out. This problem is successfully solved by installing an additional unloading relay. By the way, such a relay is installed on many cars from the factory.

To install this relay we will need: 4-pin relay with a metal ear (30-40A); 80r Wires 1.5 sq. mm; about three meters -80r relay block - 1 piece; 20r Flat male connector - 1 piece; Flat female connector - 1 piece; Ring tips - 2 pcs. Electrical tape, heat shrink, corrugation.

Fuses and relays VAZ 2110 - 2112, electrical diagrams

If some devices on your VAZ 2110 or VAZ 2112 , fuses or relays may be to blame. At the very least, the first thing you need to do is check them, and then draw some conclusions regarding the malfunctions.

Correct diagnosis of many electrical problems will allow you to accurately determine the cause of the inoperability of a particular unit. To find out what the fuses and relays of the VAZ 2110 - 2112 are responsible for and how to find the right one, read this article.

As in many other cars, in the VAZ-2112 and VAZ-2110, when the engine is turned off, the devices are powered directly from the battery. When the engine is running, voltage is supplied to the devices from the generator, which simultaneously charges the battery. If the current exceeds the permissible value or a short circuit occurs, the circuit fuse will blow. Powerful electrical appliances are connected via relays.

Causes of starter malfunction

The fundamental factors why the VAZ 2110 starter does not turn are:

Inoperative solenoid relay.
Sticking of closing elements.
Worn motor brushes.
Failure of the overrunning clutch.
The immobilizer is interfering.
The reason is in the injector.

These factors are the most complex and can be solved exclusively by removing and overhauling the unit.

Solenoid relay

See if there is voltage to the unit and try to close the starter. Does it still refuse to rev? Disconnect the alarm, it often interferes with work. Each individual unit is operational, but together it fails: this means that the entire fault is in the solenoid relay, which needs to be replaced.

Sticking contacts

If the VAZ 2110 does not start and the starter does not click, then inspect the mass and the device itself, because they also tend to oxidize. There is also a proven method: simultaneously turn the ignition key and knock on the relay with something hard. If the car starts, then the problem is that the contacts or coins are stuck. Then it is better to purchase a new relay.

Starter motor brush wear

Carefully analyze the condition of the winding and commutator. No breaks or burns should be noticeable. For performance, it is recommended to clean the commutator and armature shaft journal. If the brushes are worn out, they should be replaced as an assembly.

Overrunning clutch starter VAZ 2110

First you should look at the wires going to the battery. It is likely that a replacement can resolve the situation. If everything is in order and the VAZ 2110 8-valve injector does not start, the starter does not turn, but starts only when pushed, then the Bendix is probably to blame.

Immobilizer

Often the difficulty may lie in a working immobilizer. In this case, the blocking is simply activated and the engine stops. The only solution is to tow the car to a car service center for diagnostics.

Injector

The injector does not always accept low-quality gasoline, and repairs can be quite expensive, because the system operates via a microprocessor. In our country, this may also be the reason why the VAZ 2110 injector does not turn the starter. Flushing may be required.

Fuse and relay box

The fuse and relay box is located on the left, lower part of the instrument panel. It is accessible by pressing the button and folding the lid down. To remove fuses, there are special non-conductive pliers in the upper left part of the mounting block.

1 - K5 - high beam relay . If the high beams in two headlights do not work, check this relay. If one of the high beam headlights does not work, check fuses F3 and F13, as well as the lamps and the high beam switch.

2 - K4 - low beam relay . If the low beam in both headlights does not work, check this relay. If only one low beam headlight does not work, check fuses F2 and F12, as well as the lamps themselves and the light switch.

3 - K1 - lamp health control relay.

4 - non-conductive tweezers for removing fuses.

5 - power window relay . If your power windows stop working, check this relay. It could also be in fuse F5, or in the window lift drive system itself. To get to the mechanism, you need to remove the door trim. Check the electric motor, the appearance of the gears and the absence of binding of the mechanism.

Additional starter relay VAZ 2110

As it was already found out earlier, the Lada of the tenth family does not have a starter relay . The starter retractor is controlled directly from the ignition switch, and therefore the contact group loses good contact. Therefore, many VAZ 2110 owners install an additional starter relay . This will relieve the contact group, as well as significantly increase the tension on the retractor.

_For an additional VAZ 2110 starter relay you will need:_

4-pin relay (30-40 A);
Wires;
Flat female connector - 5 pcs;
Flat male connector - 1 piece;
Ring tips for 6 mm and 8 mm - 1 pc.

Replacing the VAZ 2110 starter relay on your own

All drivers know that without a starter, the car not only won’t move, it won’t even start. It drives the crankshaft. In this case, the shaft is accelerated to a certain frequency. As soon as the desired frequency is reached, the engine will start. One of the starter components is a two-winding traction relay. Replacing the VAZ 2110 starter relay is a mandatory procedure, because without the correct operation of this mechanism, the vehicle will not move. On a VAZ 2110, replacing the starter relay can be done on your own.

What is a relay for?

Replacing the starter relay on a VAZ 2110

The traction relay ensures that the drive gear starts. Starting occurs in clutch with the gear mechanism of the crankshaft flywheel. It also provides power to the starter motor. When the starter is turned on, energy begins to be transferred from the battery. The energy path passes through the ignition switch.

VAZ 2110 additional starter relay

In this way, power is supplied to each winding of the traction relay. Windings have two types:

As soon as the process of closing the relay contacts takes place, the retractor winding is turned off. A working relay has a voltage limit that should not exceed 8 V. The temperature during this process should not exceed 25 degrees Celsius. If the voltage when starting the relay exceeds this indicator, then you should pay attention to the drive and the traction relay itself. They may become damaged or stop working. The traction relay can be visually examined. Perhaps the breakdown can be seen with the naked eye, but the starter will have to be dismantled and disassembled.

Basic starter malfunctions

The traction relay does not operate after the ignition key has been turned, and the armature does not rotate.

In this situation, it may be due to the following possible problems:

the battery is broken or discharged, the solution to this problem is to buy a new battery or charge it;
the positive contacts have oxidized - you just need to clean them;
it happens that an interturn short circuit occurs on the winding of the traction relay - to correct this situation, you need to install a new relay;
the circuit that powers the traction relay has broken - you need to check the wires for integrity, and whether they have become disconnected from the circuit?
contacts “30” and “50” do not close - you just need to change the contact part of the ignition switch;
The traction relay armature does not work well - you need to remove it and disassemble it, there may be a lubrication problem.

After turning the key, the starter does not start, the armature rotates slowly, and a click is heard in the traction relay.

This situation may arise due to previously similar situations:

the battery is discharged or disconnected - you need to check and correct the situation;
the winding of the traction relay is shorted or broken - you also just need to change the relay;
the ends of the wires have seriously succumbed to oxidation - they need to be checked and cleaned, starting with the battery.

After turning the key, the starter armature spins, but the flywheel does not spin.

This situation arose due to the fact that:

the freewheel is slipping - you need to diagnose the starter at the stand and replace the clutch if it is faulty;
The gears on the gearbox are worn out - you just need to replace them.

The starter makes a lot of noise when the armature is spinning.

This problem arose because:

The liners on the armature or drive shaft bearings have served their service life - you just need to replace the parts that have failed;
the starter is not secured properly, and the cover could have broken - you just need to secure it or change it;
the gears on the gearbox, flywheel crown or drive have failed - you just need to change them, or immediately replace the non-functioning parts entirely.
the gear is constantly engaged with the flywheel; if the clutch on the shaft splines is stuck, it is possible that the armature of the traction relay is stuck - to solve this problem, you need to lubricate the splines with oil. And if the traction relay is stuck, then you need to either change it or use certain methods to get rid of the jam.
