Good information garth66! Any more details on "FIX #3"? How do I identify the ACC buss from the RUN buss?
After doing a site search on fan diodes I see some issues with MSD ignitions that have a similar problem. I don’t have a MSD, but I do have a Malloy Uni-Lite distributor and I recently changed the wiring. I had it connected wrong. I had the main power wire getting power after the ballast resistor. Now I have power for the Mallory connected straight to the ignition switch. The ballast resistor is still used, but only for the coil side of the circuit. Maybe the voltage drop across the ballast resistor was enough to prevent this fan run-on issue for all these years. Or maybe it is just a bad ignition switch. But I would appreciate more details on FIX #3 if you have them. THANKS.
