A short-circuit between a live cable and ground is often indicated by the loss of a function or a fuse blowing when a current is passed through the cable.

For repair of wiring and terminals, see the appropriate Wiring Diagrams.

Checks: 

Use an ohmmeter to take a resistance reading between the cable and ground.

The ohmmeter should read infinite resistance if no components are connected.

Check pins and terminals particularly for this fault. See Check terminals visually .
