Greetings again!
Long story short, both of my Buicks were 1978 Electra Limited cars, and from what I was told at my local parts store was that the wires on the OEM pick-up coils were not heavy enough to stand up to the flexing they received whenever the vacuum advance moved the "breaker plate" that the pick-up coil was mounted to. The replacement pick-up coils had visibly heavier wires than the OEM coils. After replacing the coils with after market parts, I had no more problems involving the pick-up coils. The only other problem that I had with the GM HEI was that I had one ignition coil go bad. Other than that, the GM HEI was a fairly reliable ignition system.
