Thanks. I put a multimeter to the leads, turned on the key, pressed the button, and nothing happened. I also did an OHM reading and got nothing on that as well. So it looks like it does not have a short. I may just buy a cheap horn, try to plug it in and see if that works.
I've often heard talk about fuses on a bike. I may look in the repair manual to see where they are located. Maybe someone here could help me with that problem? Where are the fuses located on a motorcycle?
There have been a couple of times, when I wished I had a horn, to alert a four-wheeler coming out of a side road. They apparently did not see me coming because, they turned out right in front of me, or misjudged my speed. Fortunately I had enough intuition to slow down some before they turned.
So a horn may not be a big deal but a minor useful safety issue, at best.
