Wiring diagrams (Chafed): General information

Chafed

Symptom

Wiring damaged or shorted to ground causing: Fuse(s) to blow, circuit(s) not to operate or not to operate correctly. Circuit operation possibly affected by dampness/moisture. Possible intermittent fuse failure.

Damaged insulation exposes wire strands

Cause

The wire(s) is chafed due to wear or abrasion against another component, e.g. body panels, brackets, suspension components, etc.

Action

Locate damaged section of wiring/harness, carefully cut back the tape or insulation from the harness with a suitable tool. If the harness has a black plastic conduit simply pull out the desired wire(s). See Repair Techniques. If only minor damage to the wire(s) insulation is present, (no damage to the bare wires) it may be OK to repair by taping up the damaged section.

Cut or Broken

Symptom

Wire is completely cut through causing: Open circuit, circuit(s) not to operate or not to operate correctly. Possible intermittent fuse failure.

Wires cut through

Cause

The wire(s) is under stress as a result of the harness being routed incorrectly, snapped by another component, e.g. a sharp edge on a bracket, or body panel.

Action

Locate damaged section of wiring/harness, carefully cut back the tape or insulation from the harness with a suitable tool. If the harness has a black plastic conduit simply pull out the desired wire(s). See Repair Techniques.
