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.

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.

In particular check pins and sockets for the relevant fault, in accordance with Check Terminals Visually Check Terminals Visually
