Basic faults
There can be many reasons for a generator malfunction on a VAZ 2110. Here, both minor damage and failure of the entire device are possible. Let's look at the list of main faults:
- Too many additional electrical devices connected. You should turn everything off and check whether the quality of the element has changed.
- If the generator does not charge, the battery may be too large. In this regard, the battery receives a charge, but does not have time to fully charge after a deep discharge.
- Short circuit of the stator or damage to the winding itself. There may also be poor connections between working parts.
- Winding break. In this case, the generator will not charge at all.
- Interturn closure. The coils may fly, so it is worth checking this in detail using a voltmeter.
- Short circuit on the rotor housing. Due to this failure, the entire winding may fail. If this happens, you will have to completely replace it.
- Short circuit in winding phase. With such a malfunction, the generator will become very hot and the battery will not be charged.
- Brush wear. The so-called “chocolate” can also fail. It can be easily replaced by purchasing it at your local auto parts store.
- The malfunction may not lie in the generator itself. The fuse may have failed and will prevent charging. Or the wire coming from the generator is broken. All this should be checked before you take out the unit itself.

How to check the generator yourself
How to check a VAZ generator using the example of model 2109. Generator type 94.3701 alternating current, three-phase, with a built-in rectifier unit and an electronic voltage regulator, right-hand rotation.
Generator connection diagram . The voltage to excite the generator when the ignition is turned on is supplied to terminal “D+” of the regulator (terminal “D” of the generator) through indicator lamp 4 located in the instrument cluster. After starting the engine, the excitation winding is powered by three additional diodes installed on the generator rectifier block. The operation of the generator is controlled by a warning lamp in the instrument cluster. When the ignition is turned on, the lamp should be on, and after starting the engine, it should go out if the generator is working. If the lamp is brightly lit or glows half-lit, it indicates a malfunction.
The “minus” of the battery should always be connected to ground, and the “plus” should always be connected to the “B+” terminal of the generator. Failure to turn the battery back on will immediately cause increased current through the generator valves and damage them.
It is not allowed to operate the generator with the battery disconnected. This will cause short-term overvoltages to occur at the “B+” terminal of the generator, which can damage the generator voltage regulator and electronic devices in the vehicle’s on-board network.
It is prohibited to check the functionality of the generator “for spark” even by briefly connecting the “B+” terminal of the generator to ground. In this case, significant current flows through the valves and they are damaged.

Generator circuit operation
This scheme is considered obsolete and is no longer used in modern cars.
Initial generator excitation
When starting, the initial excitation comes from the battery. Then, when the generator starts working, it transfers part of its current to excitation.
When the ignition is turned on, the current from the battery goes to the plus of the generator, from this point through the mounting block it goes to the ignition switch 30\1. Through the ignition switch contacts, from point 15\1, the ignition system and the generator excitation circuit are powered. Through the 19th fuse, the initial excitation current passes into the instrument panel, through the “battery discharge” light, and comes to connector D on the generator. From this connector via the additional bus. diodes goes to the voltage regulator. The voltage that reaches point L opens the regulator transistor, the excitation current passes into the rotor, and from it, through the open regulator transistor to ground. This closes the initial excitation circuit. The light comes on, confirming that the excitation circuit is intact and the generator is ready for operation. A small current of this circuit magnetizes the rotor; when the rotor begins to rotate, its magnetic poles, replacing each other, create a changing magnetic field that interrupts the turns of the stator winding and an EMF is generated in it, that is, the generator is excited.
Generator excitation during operation, additional rectifier
The voltage at the output of the generator quickly increases and becomes higher than the emf of the battery, now the generator becomes a source, it begins to charge the battery and power all devices.

Operating principle of the generator
Cars use a three-phase synchronous generator. The operating principle of the generator is based on the law of electromagnetic induction. “Electromotive force in a winding occurs when the magnetic field changes.”
The emf of the generator arises in the winding. The rotor serves to create a changing magnetic field. To magnetize the rotor, an excitation winding is built into it. Current is supplied to it through brushes.
The stator winding is three-phase, connected in a star. There is an alternating voltage at the output of the winding, but a constant voltage is required in the car network and for charging the battery, so the output of the winding is connected to a diode bridge (rectifier).

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.
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.

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.

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.

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!

The power circuit of these lamps includes a relay-breaker K3, which alternately closes contacts 49a and 49a Register on site 2. It all started with the fact that I began to be wildly annoyed by the breakdowns of the two-piece, it seemed like nothing serious had broken, but there were so many little things, damn it, which was really starting to piss me off. Locking the trunk lock. Indicator lamp for turning on the high beam.
The only nuance of switching from a carurator to an injector is the need to install additional wiring from the fuel pump to the on-board computer.
F14 - 10A - Left fog lamp. They turn on regardless of the relay activation. To prevent this situation, it is better to connect the relay control wire to the terminal from the ignition switch in red in the diagram. It is regulated only by the limit switch

Depending on the location, the wiring differs into: under the hood and in the cabin. Injector In addition to the wiring, which is identical for the carburetor and injector, the latter is additionally equipped with fuses and sensors.
This is done to reduce the load on the battery when the engine is not running and prevent its discharge. It is regulated only by the limit switch. Side light indicator lamp.
But this does not take away the fact that many have dozens of them under the hood with a carburetor. F3 - 10A - Left headlight high beam. These positions correspond to the inclusion of indicator 5 on the device. F2 - 7.5A - Left headlight low beam. Connecting the VAZ ECU harness
