Starter solenoid relay
The starter relay is called a pull-in relay. This is due to the principle of its operation - it performs the function of connecting the starting device to the electrical circuit and connecting its armature to the crankshaft. It happens like this: when no current is supplied to the windings of the device, its armature, under the action of the return spring, remains in the forward position. The same spring, through a special fork, holds the Bendix gear, preventing it from engaging with the crankshaft flywheel ring.
By turning the key in the ignition, we supply current to the winding of the device. Under the influence of an electromagnetic field, the armature is fed back (pulled into the housing), closing the starter power contacts. The Bendix gear also moves, engaging with the flywheel. At the same moment, the retracting winding is turned off, and the holding winding comes into play. The force from the starter shaft is transmitted through the gear to the flywheel, causing the crankshaft to rotate until we no longer hold the ignition key in the start position.
What functions does the solenoid relay perform:
- Protects the starter from shorting contacts in the ignition.
- In order to turn off the power to the starter in a situation where the engine is running and the key shows the “starter” mode.
- Provides relief of contacts in the ignition switch.
When the engine starts, voltage from the generator goes to the relay coil. Then the gears of the drive system begin to work, due to which a magnetic field is created. The flywheel of the propulsion system is working. The gear begins its work thanks to the holding winding, while the bolts are closed. When the key is returned to the ignition switch, the winding is de-energized, thus disconnecting the gear and flywheel. This scheme applies to modern cars, including VAZ models.
If the starter makes a loud noise, the pole or starter could be loose. In the first situation, strengthen the fastening by tightening the screw, and in the second, secure the starter. If you disassemble the starter and see that the clutch is starting to slip, then the only thing you need to do is replace the starter drive.

Replacement and removal of the electric generator
The generator on a VAZ car is removed either for complete replacement in case of failure or to carry out repair work to replace faulty parts. To perform dismantling, prepare a standard set of tools; it is advisable to drive the car into the inspection hole.
- Disconnect the battery.
- Remove the protective rubber cap from terminal “30” and unscrew the nut and remove it from the wire stud.
- Disconnect the block with wires from the generator connector.
- We loosen the tightening of the generator to the adjusting bar, then lift it all the way up to the cylinder block and remove the belt from the pulleys.
- Completely unscrew the bolt securing the adjusting bar to the cylinder block, then from the bottom of the car unscrew the 2 bolts securing the lower bracket to the block and remove the generator, pulling it out of the engine compartment.

According to the scheme described above, fuel regulation in a car is carried out. Moreover, it depends not only on the load of the valves in the engine, but also on the corresponding position relative to the throttle valve. With the help of a diagram of electrical wiring and valves, it is possible to understand which of the relays or fuses is malfunctioning and replace it in time. In this case, one of the main roles when supplying fuel is played by electrical equipment (controllers) that regulates the operation of the injector.
Description of battery operation
A battery is a device with the help of which electrical energy is obtained from chemical energy and vice versa, with the ability to accumulate and store charge. The main purpose is to provide power to the electrical equipment of an idle vehicle, as well as to start the engine using the starter. If the generator does not work or cannot cope with the load, the battery takes over its role. The generator does not allow the battery to discharge, as it is a source of recharging.
Based on the type of electrolyte, rechargeable batteries are divided into two large groups: alkaline and acidic; based on the material of the electrodes, they are divided into:
- lead;
- zinc with the addition of silver;
- nickel-cadmium;
- iron-nickel.
Lead-acid batteries are the most popular. The principle of operation of the battery is simple: thanks to chemical processes, an electric current is generated, which is necessary to start the engine. A running motor receives electricity from a generator. In this case, electrical energy is obtained from mechanical energy. The battery receives electricity from the generator and converts it into chemical energy, storing it for further use.
Each battery has two poles: negative and positive. When connecting to the electrical circuit of the car, you need to know exactly what the polarity of the battery on the VAZ 2110 is, otherwise the electrical equipment may burn out.
VAZ-2110 wiring diagram
Electrical wiring for the VAZ-2110 is of two types: carburetor and injector . There are slight differences, but the basic principles of operation and wiring are the same. Depending on the location, the wiring differs into: under the hood and in the cabin . All electrical equipment of the car is connected using wires of a certain color. Each element has its own wiring harness through the blocks and fuses.
The on-board voltage is 12V constant, minus on the car body.
Having a wiring diagram and knowing the operating principles of the main components of the car is not at all difficult to find the malfunction and the cause of its occurrence.
Before starting to repair the vehicle's electrical wiring (if this is not related to troubleshooting), the terminals should be removed from the battery.
Electrical diagram of a carburetor ignition system
At the first releases of the VAZ-2110, a carburetor was installed, which was later replaced by an injector, as a more modern and reliable system that ensures economical stable operation of the engine. The wiring of an engine with a carburetor includes almost the same vehicle life support systems as with an injector.

Electrical diagram of a contactless car ignition system
The carburetor is already an obsolete car part. It is less reliable and cannot provide such an accurate supply of the fuel mixture. In later releases, the carburetor ignition system was replaced with an injection system. The controller in this system “reads” the operation of all systems, thereby determining and setting many indicators - calculation of the fuel mixture, etc.
To find a wiring fault, you need to start looking in the contacts. Moreover, you need to check all the wires that are included in the harness: their visual integrity, resistance, reliability of contacts, etc. The underhood wiring has identical plugs.
In addition to the wiring that is provided for the VAZ 2110 - carburetor, "ten" - injector, it is also equipped with a number of fuses that protect almost all of it from the possibility of short circuiting. The fuse and relay box in VAZ-2110 cars is located in the car interior near the driver's seat, to the left and below the steering wheel.
Fuse box VAZ-2110, VAZ-2111, VAZ-2112
VAZ-2110 fuses (number, rating and what they are responsible for)
Structurally, fuses are not provided only for the supply of current by the wire from the battery, in the car starting and ignition circuit, as well as for the wire going to the generator.
To replace a faulty fuse, first find the one that has blown and be sure to eliminate the cause. After that, install a new one of the same value.
Do not replace fuses with jumpers; this may cause blocks and devices to become unusable, as well as a wiring fire!

Generator output voltage, purpose of voltage regulator
The voltage that must operate in automotive electrical equipment must be maintained at approximately 14 Volts. For this purpose, a voltage regulator is installed in the generator
The voltage regulator is included in the excitation circuit, that is, in the rotor winding circuit, so it is structurally combined with the brushes. The regulator constantly turns the excitation current on and off, thereby maintaining the required generator voltage level.
Generator voltage regulator 9402
Generator voltage regulator 5102
