Distributor Cap: Description and Operation
Rotor for bi-level distributor caps
Distributor Cap
The EEC system uses a Dura Spark III ignition module and coil to generate the required high voltage spark. The distributor cap and rotor are of a
special two level design, Fig. 1, made to accommodate the additional advance capability of this system. Both the rotor and cap have upper and
lower electrode levels. As the rotor turns, one of the high voltage electrode pickup arms aligns with one spoke of the distributor cap center
electrode plate, allowing high voltage to pass from the plate through the rotor to the terminal on the distributor cap and out to the spark plug.
The numbers, Fig. 2, molded into the top of the cap are wire identification numbers. Due to the unique design of the distributor cap and rotor, the
wires are not arranged in the cap in the firing order.
