Horn relay mod

OK, evidently the button does not short to the handlebar, but to a separate ground wire.

In that case, it makes sense, but you are still running a LOT of current through the horns switch when you push the button.

Using a relay will fix that and provide full current to the horns.

Oh, yeah!!!

Good!! I didn't use it often but, when I did, it was really loud and it made me really happy (and, sometimes safer)! That's what a horn should do....and it did!!!!!

I agree with Steve; a button or a switch should be an actuator, not a current provider. Contacts tend to burn over time. I had to disassemble and fix the starter button on an 81 KZ750 I had; it was a PITA. Fortunately I knew how they were designed from prior experience, so I was careful not to lose the spring or other tiny parts.

How many lifetimes would you have to live before you'd blow your horn enough times before you'd be sorry you did it the way I did it???

If you ride in the Orient or in Italy, it would only take a few days.

I just came back from India 3 weeks ago and, that is so true!!!!!!! If you could ever wear out a horn, that would be the place!!

On my bike I was never concerned about the switch, it's pretty crude abut has a lot of surface area. What was a concern was the tiny 18ga wire feeding it. It was easier to add a relay than to open up the harness and replace the wire all the way to the switch. I agree that to an extent "switches" should be used for control and not supply but you can also really over complicate things.
