The charge system consists of an alternator, voltage regulator, charge indicator light circuit, battery, fusible link and connecting wires. When these devices work together, power is provided to such consumers as the ignition system, lighting and signaling devices, a radio receiver, etc. The generator is driven by a belt.
Attention! Generators 1980-87 are equipped with a built-in voltage regulator, which is mounted on the side of the generator housing, access to it is possible without removing the generator.
Attention! Voltage regulator on generators 1988-92 mounted on a rectifier inside the generator housing.
Attention! On cars since 1993, the regulator is made integral with the brush holder assembly, access to the regulator is provided after removing the generator and the rear cover.
Cars 1980-87 are equipped with an ignition relay that energizes the charge and ignition circuit fuses.
Cars 1988-92 are equipped with a relay that ensures the ignition of the control lamp when the battery is insufficiently charged. On cars since 1993, additional fuses and fuses have been provided that provide monitoring of the integrity of various sections of the charge circuit.
The voltage regulator is designed to maintain the generator voltage at a given levehp a sharp increase in voltage at the output of the generator, the regulator prevents surges and overloads in the power circuit.
Periodic maintenance of the charging system is generally not required. However, you should periodically inspect the alternator drive belt, battery and connecting wires.
The charge control lamp on the instrument panel lights up when the ignition is switched on and goes out after the engine is started. If the lamp does not go out after starting the engine, then the charge circuit is faulty. Some vehicles are equipped with a voltmeter. If the voltmeter shows a very high or very low voltage, then the charge circuit needs to be checked.
Precautionary measures
When connecting the wires of the vehicle's internal circuit and external devices, observe the following precautions.
When connecting the battery to the generator, always observe the polarity of the connection.
Before repairing any part of the vehicle with electric welding, disconnect the wires from the alternator and from the battery terminal.
It is unacceptable to start the engine with the charger connected.
Always disconnect the vehicle circuit cables from both battery poles before connecting the charger.
The generator is connected directly to the battery, so if the generator leads are shorted or overloaded, arcing and fire may occur.
Before flushing the engine with a jet of steam, cover the generator with plastic wrap and secure the wrap with a rubber band.
