Just got it firing!
Hi all. I have a 2005 Nevada 750 on which the horns have been getting weaker and weaker over the last six months. They now will not work at all. (Well occasionally a faint beep). When I hit the button (ignition key on but motor not started) I see the headlight dim significantly, and I hear a low volume thud sound, not unlike you would get when trying to start the bike with a low battery.
The starter seems to be fine and the bike starts and runs normally. I removed the battery and checked the voltage, finding 12.8v across the terminals. The horns have two wires feeding each unit. They seem to be wired in series. There is good connectivity between the two horns through one wire on each, and the other wire on each horn has good connectivity to ground. There is good connectivity across the two terminals of each horn unit. I initially suspected the handlebar switch, but did a close inspection and everything looks ok.
Not sure how this circuit works, maybe through a relay, or by simply closing the loop to ground. If anyone can shed some light I would be most appreciative. Without the horn I can't get the bike inspected.
Thanks all.
