During the operation of electronic wiring harnesses, problems always occur due to various reasons. Common problems include poor contact of connectors, short circuits between wires, open circuits, and grounding. So, what are the reasons for the occurrence of electronic wiring harness problems?

1. Natural aging or damage

The wiring harness has been used for more than its lifespan, and the insulation layer of the wiring harness is slowly cracking, causing a decrease in mechanical strength. Over time, it can easily lead to problems such as short circuits, open circuits, and grounding between wires.

2. Wire harness terminal oxidation

When the wiring harness terminals are completely oxidized, they may have been deformed, which can also cause poor contact or short circuits in the wiring harness, and then cause the wiring harness to malfunction.

3. Electrical equipment malfunctions

There is also a situation where the electrical equipment is overloaded, short circuited, and then the wiring harness malfunctions.

4. Human factors

Improper human operation, such as improper positioning of wiring harness devices, incorrect wiring between wiring harnesses and electrical equipment, damage to wiring harness components during maintenance, etc.

Detection and discrimination of electronic wiring harness defects:

Ground connection: The rule for burning out electronic wiring harnesses is that at any point in the power system circuit, the electronic wiring harness will burn out. The connection between the burnt out part and the undamaged part can be considered as grounding at that point; If the electronic wiring harness is burned to the wiring part of an electrical equipment, it indicates that the electrical equipment is faulty.

Short circuit: The electronic wiring harness is subjected to external kneading and impact, causing damage to the insulation layer of the wires inside the electronic wiring harness, resulting in a short circuit between wires, causing some electrical equipment to lose control and the safety wire to blow.

When distinguishing, the electronic wiring harness connectors at both ends of the electrical equipment and the control switch can be disassembled, and a meter or test light can be used to detect the short circuit in the circuit.
