Tips and Precautions Before Troubleshooting

1. Check applicable fuses in the appropriate fuse/relay box.

1. 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 severely damage the wiring.
