Mobile WebSiteWith the development and progress of the times, the rapid increase in automobile output has promoted the rapid development of the automotive wiring harness industry in China. However, automobile safety is also increasingly important. As a core component wiring harness in automotive systems, it plays a decisive role. Reasonable maintenance and repair can guarantee you Safety of driving.
Common faults in automotive wiring harnesses include poor connector contact, short circuit between wires, open circuit, and ground.
The reasons are as follows:
(1) Natural damage
The use of wire harnesses exceeds the service life, causing aging of the wires, cracking of the insulation layer, and a significant decrease in mechanical strength, causing short circuits, disconnections, and grounding between the wires, causing the wire harness to burn out. Oxidation and deformation of the automotive wiring harness terminals may cause poor contact and cause electrical equipment to malfunction.
(2) Wire harness damage due to malfunction of electrical equipment
When the electrical equipment is overloaded, short-circuited, or grounded, it may cause damage to the harness.
When assembling or repairing auto parts, the metal objects crush the wire harness and break the insulation of the wire harness; the position of the harness is improper; the position of the lead wire of the electrical equipment is connected incorrectly; the positive and negative lead wires of the battery are connected reversely; Picking up and tangling wire bundles and wires can cause improper operation of electrical equipment and even burn out the wiring harness.
