On the pos. side of the coil with ing key on run pos. I get only 4.7 volts. I have electronic ignition on my 65 dodge truck. Its not enough to run on the run pos of key but will run on start pos. and will run if I bypass the balast resitstor. I have tried 3 different ballast resistors, no luck. sitll wont run on run circuit. I have swapped coil, ECU, ballest resitstor, distributor, and put a new ignition switch in. I know I should get 6-8 volts on run circuit, why only 4.7?? Its not enough to keep my truck running. If I bypass balast resistor with a wire, runs great. I am buying auto zone, advanced auto, ballast resitors. Should I get a mopar perf. one?? Any other place you would look for a problem??
