General Troubleshooting Information
A A A
A
1. Check applicable fuses in the appropriate fuse/relay box.
2. Check the battery for damage, state of charge, and clean and tight connections.
 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 s everely damage the
wiring.
 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.
 Before connecting connectors, make sure the terminals (A) are in place and not bent.
