Short-circuit to ground, permanent faults
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 appropriate repair information in CABLES and FUSES - REMOVAL, REPLACEMENT and INSTALLATION .
Checks:
- Activate all switches and sensors in the circuit. Check whether the fuse blows
- Disconnect the connectors in the circuit to ensure that they do not affect readings.
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 Inspect terminals visually .
