Lumina V6-3.8L VIN K (1998)
Ignition Coil: Description and Operation
DESCRIPTION
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.
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.
