Troubleshooting
Tips and Precautions
Before Troubleshooting
• Check applicable fuses in the appropriate fuse/relay
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.
Handling Connectors
• 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.
LOCKING TAB
• 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.

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.
BENT TERMINAL
• Check for loose retainer and rubber seals.
RETAINER
• The backs of some connectors are packed with
grease. Add grease if necessary. If the grease is
contaminated, replace it.
