Getting my new whip ready for inspection and discovered my horn has issues. The horn was disconnected from the bumper and now I know why. It won’t stop blowing when I hook the wire back up to the actual horn. I removed the horn assembly on the steering wheel and and for obvious reasons it stops because the mechanism is no longer grounded. I tested the ground wire on the steering wheel and can hear the relay clicking when I disconnect the actual horn so all is good with that. Everything makes sense up till now. Problem is, when I connect the ground wire the assembly and attach it to the steering wheel the horn won’t stop honking. I assume it’s staying grounded when I hook it up. Been troubleshooting it for a little while and I’m wondering what the issue might be. Any thoughts?

First--when you move the wire up the steering column so that the connector on the end is not touching a ground, does the horn still sound? If it does, you have a short somewhere and need to find it.

If that stops the horn from sounding then the circuit is probably OK.

Check for electrical connectivity between the inner metal part visible in your photo and the outer metal part that has the tab in it. There should be ZERO connectivity, infinite resistance. If you have a short there, that is the cause of the horn sounding.

There should be plastic spacers and washers between the inner and outer metal parts there. If someone put metal washers in, the screws will make contact with both and will cause them to be electrically connected together.

Lastly, make sure that the wire doesn't get pinched against any metal bits when you put the button back on the wheel, and that the rubber "boot" actually pushes the button away from the steering wheel when you're not pushing it down.
