Has the coil been swapped out? I would think a short in the coil could cause that. Also, a short in the wiring serving the distributor would almost definetly fry a module.

I've had 2 (in a row) Proform modules quit on me. Needles to say, I don't buy anything from Proform anymore.

checked wires none are exposed. also we put in 2 other distribitors and fried those too. each had it's own coil. also run a new lead wire right to the battery. i'm stumped but what do i know i'm a ford guy.

Western auto, I bought a proform module and it burnt up the second time I cranked my car. They must not be worth a ****!

One of the guys at our track had a bad tach that was shorting and burning up the coils. They unhooked the tach and have had no problems since.

Most ignition modules require a special grease be applied to the bottom of the modules .If you don't put this on you will burn the modules up. You see, the grease acts as a heat barrier.

How about the switch panel or the holder of the switch. Maybe your getting a short threw the panel from another power or accessory source, causing the modual to fail. I've run HEI on everything I've ever run and never had a hei fail unless its wore out, wired wrong, or a part in it just fails. Once they were fixed, or the part replaced I had no problems. I'm just trying to say that they are a good ignition and I would have to think there is a short somewhere else causing the modual to fail. Man can I take the long way around to explain my thought.sorry so long

You never mentioned if you were running an alternator or not.
