Distributor Cap: Description and Operation

Cut-Away View Of Distributor Cap

PURPOSE

The distributor cap makes the connection between the coil wire and the correct spark plug wire. The static shield provides radio static suppression
so the high energy sparking that occurs inside the cap does not interfere with radio transmission/reception. The shield is grounded via the
distributor cap clips. 

 
LOCATION

Clipped to the top of the distributor.

OPERATION

High tension current enters the cap through the center terminal, flows through the spring loaded carbon brush to the rotor. From the rotor it is
distributed to the four cylinder towers in a pre-set sequence and then to the spark plug wires which carry the current on to the spark plugs.
