My OE coil is fine.
It was just the Pertronix ignitor inside the distributor that went bad.
Rotor was also ok. Knew something was wrong when I watched the spark on a sparkplug go from 1 weak one to no spark at all. Have 12.0 volts from the blue wire to the positive side of the coil.
Weird but when you hook up the ignitor positive wire to it, it goes to 5.6 volts.
Even the new one but have a good spark now.
Dont know why it went bad. Only 125 miles on it.
