Sources and consumers of electrical energy installed on the vehicle are interconnected by the on-board electrical network. The main elements of the electrical circuit are connecting wires, means of protecting circuits from overloads and short circuits, means of communication (breakers and switches) and various connecting and distributing devices. The design and functions of some elements of the electrical network of cars are considered when describing specific products and systems. To protect electrical circuits from overloads and short circuits, pin-type fuses are used.
Most of them are installed in the mounting block.
The battery charging circuit, the ignition and engine start circuits, the windings of a number of relays are not protected by fuses.
Before replacing a blown fuse. it is necessary to find out the cause of the incident and eliminate it. When searching for a malfunction, it should be localized taking into account the circuits that this fuse protects.
