I was going to town to get an inspection sticker the other day. After I put the horn on I was standing outside the car when I tried it and it worked fine. When I get to Marks for the sticker I was in the car and when I pushed the stalk in it shocked the hell out of me. Of course the wife almost fell out of the car laughing. I have the green wire hooked up to the horn with another ground wire from the horn to the frame. If I unhook this ground wire of course it won't work.

It reminded me of the old British motorcycles that had a positive ground system. They would shock you if it was running and it was raining and you touched a metal part.
