The troubleshooting method of automotive wire harness ablation is as follows:

The specific location of the fault is investigated by the break of the fuse wire, because the fuse wire is used to protect the circuit of the car, and the fuse wire is burned first when the circuit of the car fails.

When designing automotive wiring harnesses, the manufacturing standards of wiring harnesses are not implemented, so that the wiring harnesses are not up to standard, or the wiring harnesses are twisted too tight when assembling the wiring harnesses, resulting in the wiring harnesses breaking.

The reasons of automobile wiring harness breakage are divided into internal reasons and external reasons. The internal reasons are that the branch design of the main line harness distribution of the automobile is too short, which leads to the wiring harness breakage during the driving process.

External causes include wiring harness modification, resulting in wiring harness breakage, or wiring harness scratching, resulting in breakage. The repair method is to break off the insulation layer of the burned wire harness, cut off both ends of the wire, and reconnect it with a wire of the same specification and length.
