Automotive electrical circuits consist of the power supply circuit, starting circuit, ignition circuit, lighting and signal device circuit, instrument information system circuit, auxiliary device circuit, and electronic control system circuit. The characteristics of automotive circuits include dual power sources, single-wire system, parallel connection of electrical components, and relays and switches connected in series within the circuit. Most electrical devices in a vehicle are protected by fuses, and the entire vehicle's electrical system is divided into several independent circuit systems based on function and working principles. This approach addresses the complexity and difficulty in analyzing the entire vehicle's electrical system. Additionally, each electrical device is equipped with its own fuse to prevent wire harness damage and potential accidents caused by short circuits.
