Q: Wire harness problem

asked by on

The wire harness has no power.

Hello. Depending on which wiring harness it is, the source of the power needs to be checked. A continuity check of the wires also needs to be done to make sure there is no break in the harness. Electrical problems need to be inspected by a qualified mechanic. Wiring diagrams, volt meters, and break out boxes are typically used for this kind of diagnosis. Depending on the extent and location of the problem, the harness may be repaired or it may need to be replaced.
