Ignition System: Service Precautions

^ When making compression checks, disconnect the ignition switch feed wire at the distributor. When disconnecting this connector DO NOT use a screwdriver or tool to release the locking tab as it may break.

NOTICE: The tachometer terminal must NEVER be allowed to touch ground, as damage to the Ignition Control Module (ICM) and/or ignition coil can result.

^ Some tachometers currently in use may NOT be compatible with this Ignition System. Consult the manufacturer of the tachometer if questions arise.
