Interesting 8 pin HEI issue

Yep In fact "as an experiment" I used the same old Mopar coil on mine that was on the car. Ran it two summers. Even without a "special" coil the HEI produces more spark than the factory points/ ECU
I am running a HEI . It was only in the car for a few hrs and it shut down like I shut the key off . Checked for spark . It was dead . Met alternator is putting out 14.9 volts . I’m wondering if it is too much for the modul.
