Dead Pertronix Coil

[Dirtrack49]

Jack Shaft,
Interesting observation. Something that I had not considered.
Maybe there is something that I am overlooking which caused the coil to fail in 9 months and about 500 miles.
As I go through this car that I bought a year ago, I am finding a lot of mickey mouse stuff done by the PO. Maybe my ignition switch is junk?
When I get another coil, I will do the checks. Thanks for the info. And thanks to everyone else for your input on this subject.
