Distributors & Ignition Systems - DELCO-REMY High Energy Ignition: Description
NOTE:
Some Chevrolet and GMC light truck models with 5.0L VIN H engines are equipped with Electronic Spark Control to combat detonation.
The Delco-Remy High Energy Ignition system consists of a battery, ignition switch, spark plugs, primary and secondary wiring and a special distributor assembly.
The distributor housing and cap contain vacuum and centrifugal advance mechanisms, an electronic control module, pick-up coil, pole piece (with internal teeth), timer core (with external teeth), rotor, distributor shaft and a capacitor for radio noise suppression.
Full battery voltage is present at the battery terminal of the distributor in either the "START" or "RUN" position, as no ballast resistance wire is used.
