How does a Hei converter work on a Chevy?

How does a Hei converter work on a Chevy?

It operates in a similar fashion to the conventional points type ignition, but relies solely on a series of electronic signals to turn on and off the primary current rather than the mechanical opening and closing of points. This task is routinely carried out by the switching transistor- located inside the ignition module.

What are the elements of a Chevy HEI distributor?

The most common elements are capacitor, resistor, and battery. Additionally, there are other elements like ground, switch, engine, and inductor. It all depends on circuit that’s being assembled. As stated previous, the traces in a Chevy Hei Distributor Wiring Diagram signifies wires. At times, the wires will cross.

Where is the HEI distributor on the cap?

Now install the distributor with the rotor pointing at the No. 1 terminal on the cap. When reconnecting the new unit, you will need to purchase and splice in a single HEI terminal connector.

What kind of wrench do I need for a Hei conversion?

A special 9/16″ offset wrench is available for this if you have a hard time reaching the bolt with a regular wrench. With the bolt loose, slide the hold-down tab back away from the distributor and pull the distributor straight up out of the engine.

It operates in a similar fashion to the conventional points type ignition, but relies solely on a series of electronic signals to turn on and off the primary current rather than the mechanical opening and closing of points. This task is routinely carried out by the switching transistor- located inside the ignition module.

Where does the ignition wire go on a Hei?

The below diagram shows a 20gauge ignition wire goes to the + post of the coil (which the HEI does away with) then to the “R” terminal on the starter solenoid. Isn’t a 20gauge wire too small for 12v?

What are the issues with converting a distributor to Hei?

When converting to an HEI there are three issues which must be addressed. The first concerns the resistance in the run circuit. The second concerns the gauge of wire feeding the HEI distributor. The third concerns the starter 12 volt override and the ignition switch. When using HEI, the distributor requires a 12 volt feed.

Where are the spark plugs on a HEI distributor?

Tip: Label or mark the location of your spark plug wires on the distributor cap for fast, easy reference. Tip: When you have installed your HEI distributor, its best to widen the plug gap as well. Tip: You should run a new power wire that is getting a full 12 volts.
