Exploded View Of Distributor:






Operation
The distributor sends a signal to the ignition module which controls the timing of the spark to the spark plugs. The signal is created when the armature, attached to the distributor shaft, rotates past the stator assembly. The rotating of the armature causes a fluctuations in a magnetic field produced by the stator assembly magnet. These fluctuations cause a voltage in the stator assembly pick-up coil. This signal is connected to the module by the wiring harness.
The signal for initial spark timing to the module is controlled by the centrifugal and vacuum advance mechanisms. the centrifugal advance controls spark timing based on engine RPM. The vacuum advance controls timing in response to engine load.
