Battery cables-check and replacement:
Periodically inspect the entire length of each battery cable for damage, cracked or burned insulation and corrosion. Poor battery cable connection cause starting problems and decreased engine performance.
Check the cable terminal connections at the ends of the cables for cracks, loose wire strands and corrosion. The presence of white, fluffy deposits under the insulation at the cable terminal connection at the battery is a sign that the cable is corroded and should be replaced. Check the terminals for distortion, missing mounting bolts and corrosion.
When removing the cables, always disconnected never negative cables first and hook it up last or the battery may be shorted by the tool used to loosen the cables. Even if only the positive cable is being replaced, be sure to disconnect the negative cable from the ground terminal on the left shock tower first.
Disconnect the old cables from the battery, then trace each of them to the remote terminals and detach them. Note the routing of each cable to ensure correct installation.
Check the cables that connect the starter solenoid and ground terminals to the remote terminals. If they require replacement, note the routing of each cable to ensure correct installation and then detach them.
If you are replacing a cable, take it along with you when purchasing a new one. It is vitally important that you replace it with an identical part. Cables have characteristics that make them easy to identify: positive cables are usually red and large and cross-section, ground cables are usually black and smaller and cross-section.
Clean all connections with the wire brush to remove rust oxidation and corrosion. Apply a light coat of petroleum jelly or greased wall fastener threads to prevent future corrosion.
Before connecting a new cable to the battery, make sure that reaches the battery without having to be stretched. Connect the positive cable first followed by the negative cable.
