66 Coronet keeps running when I turn off the key.
I have an awsome coronet that's been converted over to electronic ignition long before I got the car. It's been working great till yesterday when I shut the key off it kept running. All the other electronics shut off except the ignition. I pull the coil wire to kill the engine but if I leave the batterie conected it kills the batteriie. I changed the ballast resistor the voltage regualtor and the ignition module so far. Any thoughts? Thanks Doug 218-821-4394
