1. The wire harness burns out suddenly. The burning speed is very fast. Generally, there is no safety device in the burned out circuit. The rule of wire harness burning is: in the circuit of the power supply system, the wire harness burns wherever it is grounded, and the junction between the burned and intact parts can be considered as wire grounding; If the wire harness burns out to the wiring part of an electrical equipment, it indicates that the electrical equipment is faulty.
2. Due to poor line contact, most faults occur in the connector. When the fault occurs, the electrical equipment will not work normally. When judging, connect the power supply of the electrical equipment, touch or pull the relevant connector of the electrical equipment. When touching a connector, the operation of the electrical equipment is abnormal, indicating that the connector is faulty.
3. In addition to the obvious fracture phenomenon, the common faults of wire open circuit mostly occur between wires and wire terminals. After some wires are broken, the outer insulation layer and wire terminal are intact, but the inner core wire and wire terminal of the wire have been broken. When judging, the conducting wire and conductor terminal suspected of open circuit can be subject to tensile test. During the tensile test, if the conductor insulation layer gradually becomes thinner, it can be confirmed that the conductor has been open circuit.
4. The wire harness is squeezed and impacted by the outside, causing damage to the wire insulation layer in the wire harness, resulting in short circuit between wires, causing some electrical equipment out of control and fuse fusing. When judging, disconnect the wire harness connectors at both ends of the electrical equipment and the control switch, and use the electricity meter or test lamp to detect the short circuit of the line.
