Delco Distributor Ignition

All Delco distributor ignition (DI) systems include these essential components: battery,distributor, ignition coil, ignition switch, spark plugs,primary and secondary wiring. The DI system is connected to the ECM. The ECM monitors various engine sensors, computes the desired spark timing and signals the ignition control (IC) module in the distributor to change timing.

The high energy ignition (HEI) distributor is made up of a housing, an IC module, a pick-up coil assembly, a rotor and a cap.

The distributor used on marine engines is designed for the marine environment. The distributor base plate is equipped with 2 special vents to prevent fuel vapors from igniting. This ignition system is used on carbureted, TBI and 7.4/8.2L MPIengines.
