The task of the voltage regulator is to limit the voltage generated by the generator within the specified limits. The regulator prevents circuit overloads and other unpleasant phenomena associated with power surges.
The charging system does not require regular maintenance. However, you should periodically check the condition of the alternator drive belt, battery, connecting wiring and its terminal connections (see chapter Settings and ongoing maintenance).
The charge control lamp mounted in the instrument panel briefly turns on when the ignition key is turned to the ON position and should go out immediately after the engine is started. Failure of the lamp to turn off indicates a malfunction in the charge system. On some models, a voltmeter is additionally installed in the instrument panel, which allows the driver to timely monitor deviations of the on-board voltage from the norm. If the voltmeter readings are outside the allowable range, the charge system should be checked.
When docking the terminal connections of electrical circuits of vehicles equipped with an alternator, special precautions should be observed:
- a) When connecting the battery wiring to the generator, never reverse the polarity;
- b) When starting the engine from an auxiliary source, make sure that the polarity of the wires is connected correctly (see chapter Settings and ongoing maintenance);
- c) Before using electric arc welding for body repairs, disconnect the electrical wiring from the terminals of the generator and the battery;
- d) Never start the engine with the charger connected to the battery;
- e) Always disconnect both wires from the battery before charging from an external power source (first negative);
- f) Avoid getting hands, hair and loose clothing in contact with the rotating alternator drive belt during engine running checks;
- g) Remember that the generator is connected directly to the battery and its overloads and short circuits can ignite the wiring and cause a fire;
- h) Before steam cleaning the engine compartment, wrap the generator in a plastic bag, which should then be securely fastened with rubber bands.
