The exhaust manifold has a horn bracket on it so we found an old style horn for it. When I did the re-wire to 12 volts, I wasn't sure which terminal was which on the horn. Of course, I picked the wrong one and sparks flew. Flipped the wires, all good. Fast forward to today. We removed the front clip do to some work on the engine/transmission. After putting things back together, when I went to connect the horn again, it just honks continuously. There isn't a horn relay on this truck. Any thoughts on why it was working correctly before and now, not so much?
Thanks!

I'd check the wire coming from it to see if there's voltage present. Unless the horn is being used, there should not be any and the insulators for that horn switch are prone to rot and fall out anytime. Long years ago I did away with the old style horn but left it in place and ran the wire from the relay to a dual-tone horn behind the grille (hi/low). The new horn gives a louder noise and is a sound I think most people expect to hear from a truck horn. At least I like the sound better...
Good luck.

Cleaned the contact surfaces and reinstalled. I thing the button plate wasn't installed properly and was causing the constant ground contact. Must have gotten bumped somehow taking off the clip. Working fine now.
