The voltage regulator controls the voltage at the generator output in accordance with the engine operating mode. The regulator takes into account the vehicle speed, engine temperature, air inlet temperature, and electrical load from consumers (air conditioning, audio system, cruise control, etc.).
The charging system generally does not require periodic maintenance. However, the alternator drive belt, connectors and system wires must be inspected periodically according to the schedule specified in Chapter 1.
The discharge lamp should light when the ignition is turned on and should go out immediately after the engine starts. If it remains on, there is some fault in the charging system. Some cars are also equipped with a voltmeter. If the voltmeter registers an abnormally high or low voltage, then the charging system requires checking (see paragraph 11).
When working with vehicle electrical circuits, observe the following rules:
- a) When connecting the battery wires to the tenor, observe the polarity.
- 6) Before starting welding work on the vehicle, disconnect the wires from the generator and from the battery.
- c) Never start the engine with an external charger connected.
- d) Before connecting an external charger to the battery, disconnect both wires from the battery.
- d) The generator is driven by a belt from the crankshaft, which can cause serious injury if your clothing, hands or hair gets caught in it while the engine is running.
- e) The generator is connected directly to the battery, so if it is overloaded or short-circuited, an electric arc or even a fire may occur.
- g) When treating the engine with steam, cover the generator with a plastic bag and secure it securely.
