Well since I have had the bike the horn hasn't worked. I pulled the horns cleaned the contacts. Opened up the controls on the handlebars and cleaned it. Put it all back together and nothing. I hooked up the horns to a 12v battery and they work just fine. Measured voltage at the horns and was getting 10.35-11.2 when pushing the button. You can here the horns want to but they just make a squawking noise. I have no idea where to go on this. But being as its a safety concern I would like to fix it.
