Wire and Cable Testing

1. Check connections for looseness, rust, and stains.
2. Check terminals and wires for corrosion by battery electrolyte, etc.
3. Check terminals and wires for open circuit or impending open circuit.
4. Check wire insulation and coating for damage, cracks and wear.
5. Check conductive parts of terminals for contact with other metallic parts (vehicle body and other parts)
6. Check grounding parts to verify that there is complete continuity between attaching bolt(s) and vehicle body.
7. Check for incorrect wiring.
8. Check that harnesses are secured to prevent contact with sharp edges and corners or hot parts (exhaust manifold, pipe, etc.).
9. Check that harnesses are secured firmly to provide enough clearance from the fan pulley, fan belt and other rotating or moving parts.
10. Check that the harnesses between fixed parts such as the vehicle body and vibrating parts such as the engine are long enough to allow for vibration and movement.
