Strange Problem
I have an electrical problem that started occuring. I have a 69 F100, 302 with a Mallory Unilite distributor. When I turn off my ignition sometimes the engine keeps running. If I unplug the ignition switch it continues to run. When I unplug the black wire from the "I" terminal on the starter solenoid the engine cuts off. I replaced the starter solenoid and still have the same problem with the new one.
Any ideas?

Next time it happens, leave the ignition switch in the off position and give the voltage regulator a hard thump with a srewdriver handle. The contacts inside are pitted and sticking closed. Report your findings.

Red69,
The problem may be the lack of an external resistor for your voltage regulator. When I installed an MSD box and distributor on my 351W the MSD instructions stated that I may need to install a resistor that came in the kit to prevent engine run-on. I installed a new voltage regulatory prior to the motor swap and did not end up needing it. Hope this helps.

Ok I'll give those ideas a try. When I kill the switch the Alt. light does come on so I assumed the regulator was ok, but I'll check it. I still can't figure out why there is power on the "I" terminal of the starter solenoid all the time.
As far as the gas goes I am running high Octane because I have a 10.9:1 compression. The problem is not desieling. It still idles normal when the switch is off or even unplugged.
The regulator may be the problem because this morning when I got to work it switched off fine. Intermitant problems are a pain to locate! Anyone know if the "I" terminal is supposed to be always hot on the solenoid?
