The voltage regulator controls the voltage at the generator output in accordance with the engine operating mode. The controller takes into account vehicle speed, engine temperature, inlet air temperature, electrical load from consumers (air conditioning, audio system, "Cruise control" etc.).
The recharging system usually does not require periodic maintenance. However, the alternator drive belt, system connectors and wires should be inspected periodically according to the schedule in chapter 1.
The discharge lamp should light up when the ignition is turned on, and should go out immediately after starting the engine. If it continues to burn, then there is some kind of malfunction in the recharging system. Some vehicles are also equipped with a voltmeter. If the voltmeter registers abnormally high or low voltage, then the charging system needs to be checked (see paragraph 11).
When working on vehicle electrical circuits, observe the following rules:
- A) When connecting the battery wires to the tenor, observe the polarity.
- 6) Disconnect the wires from the alternator and from the battery before starting welding work on the vehicle.
- V) Never start the engine with an external charger connected.
- G) Disconnect both wires from the battery before connecting an external charger to the battery.
- d) The alternator is driven by the crankshaft by a belt, which can cause serious injury if your clothes, hands or hair get caught under it while the engine is running.
- e) The alternator is connected directly to the battery, so if it is overloaded or there is a short circuit in the circuit, an electric arc and even a fire can occur in it.
- and) When steaming the engine, cover the generator with a plastic bag, securing it securely.
