GM HEI mopar dizzy hybrid

In the early-mid 90's I was messing around with putting electronic ign on a friend's I-H Scout. I tried to use a Stinger conversion pick-up with an HEI 4 pin module, but didn't get consistent spark. Signal strength was the first thing that I checked and I found that the GM inductor assem. output a pretty consistent 1 VDC while the Stinger parts were usually less than that, so I put a whole Ford D-S II system in the stock I-H dizzy body and he has not had a problem since (other than when the pick-up wires made contact with the spinning reluctor).

Fast-forward to a couple months ago I did the HEI module conversion in prep for going to a TBI on the Valiant's / 170. Worked fine right up until, but not past when I cooked the JY module from trying to use copper based anti-seize for the thermal grease. Still running on a new CarQuest module, with thermal grease in place.

The ironic thing is that the Stinger Conversions used Mopar pick-ups and their reluctors looked to be extremely similar to Mopar parts. So my old problem probably wasn't a signal strength problem. I'd hazard a guess that it was a coil impedance mismatch problem, but I don't really know.
