I agree! Yeah lets say it will not start and run without the jumper wire and it continued to run when I turned the key off with the jumper wire still connected, once I disconnected the jumper it did quit running!
71 duster 225 does not want to crank, but new ballast resistor on it ohms at 1.7 ohms.
Got it to crank and run with a jumper wire to positive side of the coil, when I turned car off it continued to run, any ideas? coil switch or something else?
