When did your ignition module fail?

I had an interesting deal, thought it was my module on a stock '80 W150, it would occasionally not start or die like it's spark but the module tested good. It ended up being the wheel pickup "eye" in the distributor had come un-riveted from the slide plate & could move evough not to read the wheel.

HEI units, jumped a car once & the person insisted on them hooking theirs up, they barely touched + to a fender lip while hooking up & mine died & it killed the module. I dropped a complete distributor about 1' to the ground on its side while swapping a motor & it lost the low side of the module & would only run above 2500rpm. Very weird, it was nothing or idle at 2500 & run fine from there up.

I run a Mallory dual point now in my daily.
