The charging system consists of an alternator, a voltage regulator, a battery, a fuse link and connecting wires. When these devices work together, they supply power to consumers such as the ignition system, lighting and signaling devices, a radio receiver, etc. The generator is driven by a belt at the front of the engine.
The voltage regulator is designed to maintain the generator voltage at a given level. If the voltage at the generator output increases sharply, the regulator prevents current surges and overloads in the power supply circuit. Periodic maintenance of the charging system is usually not required. However, the generator drive belt, battery and connecting wires should be inspected periodically. The charge indicator lamp on the instrument panel lights up when the ignition is turned on and goes out after the engine starts. If the lamp does not go out after the engine starts, the charging circuit is faulty. Some cars are equipped with a voltmeter. If the voltmeter shows very high or very low voltage, the charging circuit needs to be checked.
Precautionary measures
When connecting the vehicle's electrical system wires and external devices, the following precautions must be observed.
When connecting the battery to the generator, always observe the correct polarity.
Before repairing any part of the vehicle with electric welding, disconnect the wires from the generator and battery.
Do not start the engine with the charger connected.
The generator is connected directly to the battery, so if the generator terminals are shorted or overloaded, an arc may form and cause a fire.
