In the course of running, the electronic wiring harness always breaks down for various reasons. Common faults include bad contact of connectors, short circuit between conductors, open circuit, grounding, etc.

So,What is the cause of electrical wiring harness failure?

1. Natural aging or damage

The use time of the wire harness has exceeded the service life, the insulation layer of the wire harness begins to crack slowly, and the mechanical strength begins to decrease. After a long time, it is easy to cause short-circuit, open circuit, grounding, and other faults between the wires.

2. Wiring harness terminal oxidation

When the wiring harness terminal is completely oxidized or has been deformed, it will also cause poor contact or short circuit of the wiring harness, which will cause the wiring harness to malfunction.

3. Failure of electrical equipment

Another situation is that the electrical equipment is overloaded and short-circuited, which causes the wiring harness to malfunction.

4. Man-made reasons

The last cause of failure is improper human operation, such as the improper installation of the wiring harness, incorrect wiring of the wiring harness and electrical equipment, and damage to the wiring harness components during maintenance.
