Short-Circuit to Ground, Intermittent Faults

Short-circuit to ground, intermittent 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 as required, using appropriate procedures.

Checks:
- Check the cables visually according to "Inspect 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.

Connect an ohmmeter between cable and ground. The ohmmeter should read infinite resistance if no components are connected.
Shake the cable lightly and pull on connectors during measurement to locate the damage.
If the value is not correct, try a new cable and/or continue according to "Contact Resistance and Oxidation".
