I'd like some troubleshooting help with my HEI conversion please.

I though I should be able to do a 'quick and dirty' test of the coil by running power to the positive terminal on the coil and then taking a jumper from the negative terminal and tapping it on and off quickly to ground. An old points type coil will make sparks if you do this. Anyway, no joy with the coil in the car or with the the new spare I have. Both coils test out OK with an ohmmeter.

Am I missing something?


A condenser. Without it the magnetic field collapses much slower reducing the output.

There's no condenser in the HEI conversion so I don't really understand how this applies.

I did just punt and replaced the coil with a spare I had. All good and the car is now sold.

The HEI doesn't need a condenser as the switching transistor can positively stop the current flow without one. With a mechanical switch like points or your loose wire the inductive arcing makes for a relatively slow collapse of the magnetic field. And the part of the energy in the magnetic field which arcs across the switch is energy not transferred to the secondary.

Most all accessory power is cut during cranking. If you don't believe me then feel free to disconnect the big starter cable at the starter, turn the key to start and observe the effects. The easiest way to trigger an HEI relay is to connect both IGN 1 and IGN 2 together (already done on coil side of ballast resistor) and trigger the relay from that.

Ok. Good to know. Thanks! That's easy enough to rewire.

I kept the IGN1 and IGN2 separate with 2 relays because I am running an electric fuel pump and need IGN1 to go through the oil pressure switch.

If you need relays, SlantSixDan can fix you up.

Did this on a 83 D150 last year. Ran great for about a year. Backed up a small hill....heard a pop noise and truck stalled. Now wont restart. Does anyone have the exact testing procedures for the dizz, ICM, Coil? Thanks

Not sure why but blew a module the other day. I was testing speak plugs and wires, while running, and out of nowhere it just stopped. Swapped to a new module (had a spare!!) and it fired right up. Any ideas?

Hello, all. I'm working on a 1984 Dodge D150 and I may have missed while combing through this lengthy discussion, however, after reading, I'm planning on converting from the Lean burn to the HEI here soon, and I have seen some reference to needing a earlier style carburetor due to the current set up not having a vacuum hook up for the distributor. Can anyone recommend a carb to use?

I recommend a late 70s Holley 1945. It will be the closest to the stock carb for your truck and will be the most likely to be a direct fit for your old carb.
