Ignition Coil: Description and Operation
Ignition Coil Assembly
Ignition System
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. The ignition coils share 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.
