Well, I got my lights and my brake light all working great. Last night my horn was working somewhat...so I thought. Today I tried my horn and in order to hear it you have to put your ear up to the damn thing. I have my switch wire to the horn, a power wire to the horn, and the horn ground wire thats on the switch to a ground. It is wired correct I believe but no go. Like I said, when I push the button, it works, just not good enough to do anything. Last night it was alot better...wiring has stayed the same. Is there a way I can test the horn some how? I hooked up a postive wire from a 12v car battery and a negative wire from a 12v car battery and hooked it up to the horn and it didn't come on. I was under the impression that would make it run constant and at its full potential. Here is a link to my horn. Thanks.http://www.procycle.us/images/dualsport/horn.jpg Oh, and its a 2 terminal.
