Ignition Coil

Coils are oil filled and are energized whenever the ignition switch is in the "ON" or "START" position. They contain a positive "BATT" terminal and a negative "TACH" (sometimes called "DEC") terminal and a single secondary terminal. A special connector attaches the green wire from the control module to the negative terminal ("TACH") and the wire from the ignition switch to the positive terminal ("BATT"). The wire from the ignition switch contains a 1.1 ohms resistance wire.
