Tues, I changed out the starter to send Andrew back the one he lent me. I backed out of the greenhouse and shut it off. The alternator light stayed on with the key off. I turned the key several times, but the light stayed on. I started it up and turned the key off and it kept running! I stopped it by letting the clutch out with my foot on the brake. After that, it started and stopped without any problem. I know this is going to come back to bite me. Does it sound like the ignition switch to you?
