To avoid failure of semiconductor elements of electrical equipment, follow these recommendations:
- before carrying out any work on maintenance and repair of electrical equipment, be sure to disconnect the wire from the negative terminal of the battery;
- while the engine is running, do not disconnect the battery, alternator or any connectors;
- do not allow the engine to run with the generator disconnected from the electrical circuit;
- when carrying out electric welding, disconnect the wire from the negative terminal of the battery;
- do not check the health of the generator by shorting it to «mass».
Sources and consumers of electrical energy installed on the vehicle are interconnected by wires forming an on-board electrical network. The main elements of the electrical circuit are connecting wires, means of protecting circuits from overloads and short circuits, switching means (breakers and switches), various connecting and distributing devices. The design and functions of some elements of the electrical network are considered in the description of specific devices and systems.
Fuses are used to protect electrical circuits from overloads and short circuits.
