  1. Check the main wiring harness. Check the wiring insulation for damage from chafing or heat. Also check for kinks. Reroute, repair, or replace the wires as needed.
  2. Check all the tie straps for breakage or damage. Replace any broken or cracked tie straps.

    3. Notice: Do not use flat-strip aluminum tie straps for holding electrical wiring. The sharp edges on these tie straps may cause breaks in the wire insulation, allowing the aluminum tie strap to make contact with the wire. This could cause a short circuit and damage to the wiring.

  3. Check all clamps, plastic connectors, and grommets. Replace any that are damaged. Make sure all grommets are fully seated.
  4. Check the battery cable connections on the starter for tightness. Make sure they are free of corrosion. Add dielectric grease as needed.
  5. Check the magnetic switch terminals and connections for tightness. Protect the magnetic switch terminals with dielectric red enamel as needed.
  6. Check the wires of all sensors mounted on or near the engine. Make sure no wires are closer than 6 inches (15 cm) to hot surfaces. If any are, and they cannot be rerouted, make sure they are protected by heat shields. Check the sensor connectors. Make sure they are tight, clean, and undamaged.
