Hello , I feel bad about asking this question after restoring the 1930 cabriolet to the point ready to drive down the road. I rebuilt the sparton horn and mounted it to the light bar under the head light. When I tested it off the car it worked great ! When I put the yellow wire from the cut out on the generator and the horn button wire on It starts to smoke and not work. It sparks when you touch the horn to the horn mounting bar when wires are connected to the horn.

Do I need to clean some paint of the horn mtg bracket?
