How do you hook up a HEI distributor?

How do you hook up a HEI distributor?

The easiest way to do it (and the way I did mine) is to find a connection on the back side of the ignition switch that has 12V when the key is in the “start” AND in the “run” position. Make up a 12 gauge wire with an in-line 20 amp fuse. Connect that wire from the ignition switch directly to the BAT position on the HEI.

How do you wire a HEI ignition switch?

You have to eliminate the “ballast resistor” from the circuit. The easiest way to do it (and the way I did mine) is to find a connection on the back side of the ignition switch that has 12V when the key is in the “start” AND in the “run” position. Make up a 12 gauge wire with an in-line 20 amp fuse.

What are the colors of the HEI distributor?

On a factory HEI, the primary coil leads will either be white and red, or yellow and red. The colors of the leads determine the direction the coil is wound, which determines its polarity. Whenever you are replacing a coil or distributor, it’s always a good idea to be sure to the ground clip is transferred from the old cap to the new.

Can a Hei be connected to a tach?

Connect that wire from the ignition switch directly to the BAT position on the HEI. You do not have to connect anything to the TACH position, but if you want a tach, most semi-modern tachs (like my Sun Super Tach III) work just fine when connected to the TACH output.

What’s the normal ohms reading on a Hei coil?

Disconnect the green and white wires from the module and touch the positive meter lead to the green wire and the negative lead to the white wire. The normal reading should be between 800 – 910 ohms. Testing the primary circuit of the coil.

What to do when your HEI distributor starts to fire?

If the battery is fine, make sure the wire feeding the distributor is sufficient. To make sure it is not the hot wire, run a temporary jumper wire directly from the positive side of the battery to the distributor. If the distributor fires using the jumper wire, run a new hot wire from your switched 12-volt source to the distributor.
