Do you need a coil with HEI distributor?

Do you need a coil with HEI distributor?

Most—but not all—HEI systems have the ignition coil mounted in the distributor cap. A control module and magnetic pickup are mounted in the distributor, in place of a conventional ignition system’s breaker points and condenser.

How many amps does a HEI distributor draw?

Actually, an HEI draws only 2- to 3-amps, compared to the approximate 6-amps an external oil-filled coil draws. The lower amperage draw results in a much cooler running HEI coil.

What year did GM start using HEI ignition?

General Motor’s HEI distributors are still going strong. GM’s High energy ignition (HEI), designed and built by the Delco-Remy division of General Motors starting in 1974. These units were used on all engines in 1975 through the mid-1980s, with several different variations over the years.

How many amps does an ignition coil draw?

Ignition Coil (single oil-filled coil older vehicle) – 3 to 4 amps. Ignition Coil (single DIS coil newer vehicle) – 5 to 6 amps at peak output. Ignition Coil (coil-on-plug) – 6 amps per coil at peak output.

What does Hei stand for in distributor?

HEI stands for “High Energy Ignition” or, Electronic Ignition. It can replace “points type” ignitions. This covers a broad range of automotive manufactures and companies that make this type of distributor system.

How to wire HEI distributor?

Connect the primary wires to the HEI distributor,via a plug that snaps into the distributor cap.

  • Insert the spark plug wires in the proper order on the distributor cap. The proper order depends on the specific vehicle.
  • Locate the distributor’s rotor button under the cap and determine its direction.
  • How many volts on a HEI distributor?

    The HEI just uses 12 volts . If it’s wired like points it will work on 9 volts but has problems being consistent especially at higher RPMs. If this has the GM HEI module, a high speed miss is not uncommon, it’s just on it’s upper limit.

    What is a HEI distributor?

    The HEI is a complete distributor that uses a large distributor cap with male terminals. It has a built in ignition module and ignition coil. This is an electronic distributor and is “self-contained.”.
