Distributor: Description and Operation

PURPOSE
The Distributor supplies two functions:
^ Distributes secondary voltage from the coil to the correct spark plug wire and spark plug.
^ Houses the Pickup Coils.

OPERATION
The Distributor, rotating at camshaft speed, allows the secondary voltage to flow from the coil wire through the cap/rotor to the correct spark plug wire and plug. It then continually advances the rotor to align with the next spark plug wire and plug. It also allows the Pickup Coils to accurately Inform the Engine Control Module (ECM) of the relative positions of the crank, cam and pistons.
