1) Detection and judgment of burnout failure of wire harness

Such as: computer wiring harness wiring harness burnout, all of a sudden, and the burning speed is very fast, burnt out the line, generally there is no safety device. The rule of burnout of a wire harness is: In the circuit of the power supply system, the wire harness burns wherever it is grounded. The junction of the burned and intact part can be considered as the ground of the wire; if the wire harness burns out When it comes to the wiring of an electrical equipment, it indicates that the electrical equipment is faulty.

2) Detection and judgment of burnout failure of wire harness

Such as: computer wiring harness wiring harness burnout, all of a sudden, and the burning speed is very fast, burnt out the line, generally there is no safety device. The rule of burnout of a wire harness is: In the circuit of the power supply system, the wire harness burns wherever it is grounded. The junction of the burned and intact part can be considered as the ground of the wire; if the wire harness burns out When it comes to the wiring of an electrical equipment, it indicates that the electrical equipment is faulty.When judging, you can disassemble the wire harness connector at both ends of the electrical equipment and the control switch, and use a meter or test lamp to detect the short circuit of the line. -The wire is broken. In addition to the obvious break phenomenon, common faults often occur between the wire and the wire terminal.After some wires are disconnected, the outer insulation layer and the wire terminals are intact, but the inner core wires of the wires and the wire terminals have been opened.In the judgment, a tensile test may be performed on the conductive wire and the wire terminal that are suspected of being disconnected. During the tensile test, if the wire insulation layer is gradually thinned, it can be confirmed that the wire is open.The contact of the circuit is bad, and most of the faults occur in the connector. When a fault occurs, it can cause electrical equipment to malfunction.When judging, turn on the power of the electrical equipment, and touch or pull the relevant connector of the electrical equipment. When a certain connector is touched, the electrical equipment works suddenly and abnormally, indicating that the connector failure.
