Can someone confirm how I did this?
I've managed to smoke two HEI coils. It's in a race car, so there's
minimal wiring, but in both cases the car has sat with the ignition on
and the car not running while I worked on other stuff. (it got left on
by accident for over an hour.) Eventually the coil gets HOT - I melted
one bad enough it actually melted a hole in the cap.
I have three switches in the Camaro - one for main power, one for
ignition (coil) and one for the starter. The ignition and starter are
only live if the main switch is on.
I wrote the first one off as shorted from race damage, but the second
one happened yesterday while I was working on a fan shroud - am I
shorting something out????
I don't quite know how to explain it, but is it because the coil is
energized it generates heat and doesn't ever discharge? I really don't
know what's the deal here... but that's two coils that were hot as heck...
