It was a beautiful day in the New York today, so I gave my 81RS a good cleaning. I took the horns off, but when I put them back on, they did not work. I know the horns are fine. Is there a fuse for the horn?
Yes. The horns use the same fuse that power the voltmeter, turn signal relay, and probably something else. Be sure your grounds are fine...the horns should ground at the horn attachment. Always check the last area you were working in.
