Wire harness
1. Outline drawing
2. Working principle
The wire bundle consists of wires of various specifications, connector sheaths, terminals,
conduit pipes, tapes, fuse and other parts of various specifications through bifurcation,
riveting, wrapping and assembly. Through the connection of wire harness, the electrical
and electronic equipment of the whole vehicle can work normally.
3. Basic parameters
The on-off status of all colored wires shall conform to the electrical wiring diagram;
Each fork and terminal shall be riveted firmly and connected well; The conduit pipe and
tape shall be tightly wrapped without looseness;
All connectors and corresponding electrical and electronic equipment shall be reliably
connected.
4. Possible failures
Failure assembly of the terminal and connector and loose;
Damaged wire sheath short circuit to ground or short circuit with adjacent wires; Rusted
connection at the forks is unreliable or broken;
Instantaneous failure and poor contact of wire head or wire (most instantaneous electrical
failures are caused by this); The fuse is in poor contact or burnt out;
Unstable installation of wire harnesses on the body of the car to tie the turn, causing the
wire vibration wear loss or poor contact
