I have a 1969 GTO. I can start the car fine, but when I try to shut it off it continues to run. I can even take the key out of the ignition cylinder. I stop the engine By starving the car of air by covering the carburetor. Once the engine stops, the Oil and Gen lights come on in the dash. I have to disconnect the battery otherwise the battery will drain. When I reconnect the battery, Oil and Gen lights come on again, but the car starts fine and the process repeats itself.

I have read about alternator feedback. Any idea on how to test the alternator to see if that is the problem. Also, is there a way to test the ignition system or ignition switch to see if that’s the problem.

Thank you for all your help.
