Detection and Judgment of Burnout Fault of Wire Harness:
Wire harness burned, are suddenly occurring, and the burning speed is very fast, burned the line, the general no insurance device. The law of the wiring harness is: in the circuit of the power supply system, where the ground wire, the wiring harness burned where the burned and intact parts of the junction, can be considered this is the wire; if the wire bundle burned To the wiring of an electrical equipment, it indicates that the electrical equipment failure.
Line between the short circuit, open circuit, bad contact detection and judgment. The wire harness is externally squeezed and impacted, causing damage to the wire insulation within the wire harness, resulting in a short circuit between the wires, making some electrical equipment out of control, and fuse blown.
Judgment, you can open the electrical equipment and control switch at both ends of the wiring harness connector, with a meter or test light to detect the short circuit of the line.
Wire break fault, in addition to the obvious fracture phenomenon, the common fault occurred in the wire and the wire between the terminals. Some wires are broken, the outer insulation layer and the wire terminal is intact, but the wire inner wire and the wire terminal are broken. Judgment, you can doubt the broken wire and wire terminal to do the tensile test, in the tensile test process, if the wire insulation layer gradually thinner, you can confirm that the wire has been shorted.
