[Pat/Ohio]

When I installed a new wiring harness and light switch cover, my horn would sound when I connected the battery. After doing some research on the new light switch covers (repro) I discovered that my light switch cover wasn't mated correctly and the end of the horn rod was resting against the metal in the cover. I ground a little of the bottom cover off (as instructed by Brattons) and was able to securely and evenly install the bottom half of the cover which placed the horn rod in the center of the switch. Problem went away.

Good Luck,
Pat
