● Types of automobile wiring harness faults
● Natural damage
When the wire harness is used beyond its service life, the wire is aged, the insulation layer is broken, and the mechanical strength is significantly reduced, resulting in short circuit, disconnection, and accumulation of iron cores between the wires. The wiring harness terminals are oxidized and deformed, resulting in poor contact, which will cause the electrical equipment to fail to work properly.
● Electrical failure leads to damage to the wiring harness
When overload, short circuit, and ground fault occur in electrical equipment, it can cause damage to the wiring harness.
● Human failure
When assembling or repairing auto parts, metal objects crush the wiring harness and break the insulation layer of the wiring harness; improper wiring harness position; misconnection of the lead position of electrical equipment; reverse connection of battery positive and negative leads; The electrical equipment operates abnormally, and even burns the wiring harness.
