Troubleshooting

Tips and Precautions

Before Troubleshooting
•   Check applicable fuses in the appropriate fuse box.
•   Check the battery for damage, state of charge, and clean and tight connections.
•   Check the alternator belt tension.
CAUTION:
•   Do not quick-charge a battery unless the battery ground cable has been disconnected. Otherwise you will damage the alternator diodes.
• Do not attempt to crank the engine with the battery ground cable loosely connected or you will severely damage the wiring.
While you are working
•   Make sure the connectors are clean and have no loose wire terminals.
•   Make sure multiple cavity connectors are packed with grease (except watertight connectors).
•   All connectors have push-down release type locks.

• Some connectors have a clip on their side used to attach them to a mount bracket on the body or on another component. This clip has a pull type lock.
• Some mounted connectors cannot be disconnected unless you first release the lock and remove the connector from its mount.

•   Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.
•   Always reinstall plastic covers.

•   Before connecting connectors, make sure the terminals are in place and not bent.

•   Check for loose retainer and rubber seals.

• The backs of some connectors are packed with grease. Add grease, if it's needed. If the grease is contaminated, replace it.
