How often do you service your car's wiring harness Is a broken wiring harness connected or replaced with a new one?

Wire harness refers to a component in which the contact terminals made of copper are crimped with wires and cables, and then an insulator or a metal shell is added on the outside, and the wire harness is bundled to form a connection circuit. The automobile wiring harness is the main network of the automobile circuit. Without the wiring harness, there would be no automobile circuit. So how often is the automobile wiring harness maintained and if the automobile wiring harness is broken, should it be connected or replaced with a new one?

------------------------------------------------------------------------------------------------

1. How often should the automobile wiring harness be maintained? It needs to be maintained every 40,000 kilometers. The maintenance of automobile wiring harness requires the combination of wiring harness safeguarding agent, which can prevent oxidation and moisture. The safeguarding agent also has high voltage resistance and insulation properties, which can prevent the aging or cracking of the wiring harness. Automobile wiring harness is the main network of automobile circuit operation. Without wiring harness, automobile circuits cannot be formed. The key to the wire harness is the contact connector made of copper punching, which is connected with wires and cables. A metal shell or plastic insulator is added on the outside, and finally the circuit components are connected in the form of wire harness bundling. 2. If the automobile wiring harness is broken, should it be connected or replaced with a new one? If it is normal wiring, there is no problem. If the wiring harness is broken, it is directly reconnected. If it will affect normal wiring, it needs to be replaced with a new one. The causes of automobile wiring harness breakage are divided into internal causes and external causes. 1. The internal reason is that the branch line of the main harness of the car is designed to be too short, which causes the wiring harness to break during driving. When designing the automotive wiring harness, the manufacturer failed to implement the manufacturing standards of the wiring harness, which made the wiring harness substandard, or twisted the wiring harness too tightly when assembling the wiring harness, resulting in the wiring harness breaking. 2. The wire harness was modified due to external reasons, causing the wire harness to break. Or the wiring harness is scratched, resulting in fracture. The repair method includes cutting off the burned-out insulation layer of the wire harness, cutting off both ends of the wire, and reconnecting it with wires of the same specification and length. Or when wiring, divide the two ends of the wire into two halves, tighten them close to the wire respectively, and then wrap them with insulating tape.
