HEI eats modules - Whats wrong?

[beaterC10]

I have replaced the module in my HEI two times since Easter. Both times the truck ran fine and then would not start after sitting. The truck is an 84, with an older 350. The original ESC has been unplugged and a non ESC HEI is installed.

It looks like all I need is the original power lead installed? There is another plug that piggybacks the power plug, but it goes to either the ESC connector or the 700r4 connector. The original 700r4 was replaced with a 350 before I bought the truck.

I have used this same dizzy in an 83 that had the ESC unplugged and had no problems. The first module was a made in Hong Kong "performance module" the last one was a made in USA stock replacement. Am I just unlucky or is there something I should look at?

I have seen postings on reworking the ESC wiring when a non-ESC HEI installed what is the purpose of that? Any ideas?
