Ignition Coil: Description and Operation
Ignition Coils And Ignition Control Module
Three twin-tower ignition coils are individually mounted to the ignition control module. Each coil provides spark for two plugs simultaneously (waste
spark distribution). Each coil is serviced separately.
Two terminals connect each coil pack to the module. Each coil is provided a fused ignition feed from the 15 amp ELEK IGN fuse. The other terminal at
each coil is individually connected to the module, which will energize one coil at a time by completing and interrupting the primary circuit ground path
to each coil at the proper time.
