Ignition System: Service Precautions

CAUTION:
- Do not quick-charge a battery unless the battery ground cable has been disconnected, or you will damage the alternator diodes.

- Do not attempt to crank the engine with the ground cable disconnected or you will severely damage the wiring.

- Do not pull on the wires when disconnecting a connector; pull only on the connector housings.
