Bad Coil Trouble Shooting
Phil asks:
Gary Boone EI Dizzy--Cars runs fine for awhile then dies. You let it sit and it starts up again and eventually dies. Voltage at coil while running is over 12 volts.
Mike aka exit64 says:
Sounds like you have a coil going bad. Start her up after dark and look for arching from the primary over to the secondary leads. I had one do the exact same thing once and about drove me over the edge trying to find the problem. Although it was in a Triumph with a Lucas coil so that should tell you something. Evil or Very Mad What happens is the coil builds up a charge like a capacitor and then stalls the car, after the car has been off for a few minutes it looses the charge, starts up like nothing is wrong and then starts the whole process all over again.
