Re: Distributor wiring puzzle

I suspect that it might be coming through the "GEN" light bulb. Try turning on the radio or heater blower and see if it shuts off then. The load of a radio or blower motor could be enough to drop that voltage and allow the relay to open. Years ago I built a home-made CD ignition for my car and got the same result as you have. Turning on the radio was enough to suck up the extra power going to the ignition.
