- Intermittents are usually caused by one or more of the following conditions:
- Poor electrical connections.
- Terminal tension.
- Wiring problems.
- Carefully inspect the suspected circuit for the following conditions:
- Poor mating of the connector halves.
- Terminals backed out or not fully seated in the connector body.
- Improperly formed or damaged terminals. Test for poor terminal tension.
- Poor terminal-to-wire connections including terminals crimped over insulation. This requires removing the terminal from the connector body.
- Corrosion or water intrusion. Pierced or damaged insulation can allow moisture to enter the wiring. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits.
- Wires that are broken inside the insulation.
- Pinched, cut or rubbed-through wiring in harness.
- Wiring that is in contact with hot exhaust components.
- Repair condition as necessary.
