Short-Circuit to Ground, Permanent Faults




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.

Repair wiring and cable terminals, using appropriate procedures.

Checks:
- Check terminals visually.
- 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 "Check Terminals Visually."
