Failure Of The Wiring Harness
Nov 02, 2018

The common faults of the automobile line are: The mating parts are in bad contact, the short circuit between the wires, the circuit breaker, the iron and so on.

There are several reasons for this:

1) Natural Damage

The use of wire harness over the use period, so that the wire aging, insulation rupture, mechanical strength decreased significantly, resulting in short-circuit between the wires, circuit breakers, iron, etc., causing the wiring bundle burned.

2) damage to wiring harness due to malfunction of electrical equipment

When the electrical equipment overload, short-circuit, take iron and other failures, may cause the wiring harness damage.

3) Human fault

When assembling or overhauling the automobile parts, the metal object will crush the wire bundle, so that the insulation layer of the wire bundle is broken; the battery positive and negative pole leads the reverse; When the maintenance circuit is faulty, random connection and disorderly cutting wire harness wires can cause the abnormal work of electrical equipment.
