Tips and Precautions
Before Troubleshooting
1. Check applicable fuses in the appropriate fuse/relay box.
2. Check the battery for damage, state of charge, and clean and tight connections.
NOTE:
-
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.
Handling Connectors
-
Make sure the connectors are clean and have no loose wire terminals.
-
Make sure multiple cavity connectors are packed with dielectric grease (except watertight connectors).
-
All connectors have push-down release type locks (A).
-
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 bracket (A).
-
Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.
-
Always reinstall plastic covers.
