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 waterproof 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 con-
nector from its mount bracket.
