The basic situation of the car wire harness and how to repair it!
car wire harness common faults are: poor contact with the connector, short circuit between the wires, open circuit, ground and so on.
There are several reasons for the following reasons:
1) natural damage
Wire harness use more than the use of the period, so that the wire aging, insulation rupture, mechanical strength decreased significantly, causing short-circuit between the wires, open circuit, ground, etc., resulting in wire bundles burned. car wire harness terminal oxidation, deformation, resulting in poor contact, etc., will cause the electrical equipment can not work properly.
2) Damage to the wiring harness due to failure of the electrical equipment
When the electrical equipment overload, short circuit, ground and other failures, may cause damage to the wiring harness.
3) human failure
Assembly or maintenance of auto parts, the metal objects will crush the wire harness, the wiring harness insulation layer rupture; wire harness position improper; electrical equipment lead position wrong; battery positive and negative lead wire reverse; overhaul circuit failure, chaos Then, chaos cut wire harness wires, etc., can cause electrical equipment is not working properly, or even burn the car wiring harness
