Ignition problems? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

TheRedBarron · 08-27-2017, 10:09 PM

Having an issue with my 62 C20 not turning off the ignition when I turn the key to off. All the electrics stay on even with the key in the off in the off position. It happened to me twice before, but when I drove the truck and parked it again it worked fine.... Just now it hasn't been turning off for the past four days. How would I check for a short? Should I suspect the ignition switch and relay?

Thanks for the extra links, there was a few that I didn't see. I think I can eliminate the alternator as I kill the truck in third gear to stop it, but the electrics stay on, which doesn't seem to be a topic that was on that list. I'm thinking it's either a short or the switch.... So I bought one from Napa. Let's pray to the classic car gods that it's just the switch and I won't have to go chasing wires.

Do you have a voltage regulator or an internal voltage regulator in the alternator?

I'm assuming internal, because I don't see a regulator.

Did you read the threads about the diode?
