That was exactly what my problem was. I followed the manuals instructions for testing the horn electrical system and it lead me to the horn switch. Which when taken apart was rusty and not making a good ground for the horn spring........I think it is the ground where the spring rests againist the nut behind the button
When I got my deuce the horn didn't work either. I used the TM and troubleshot using a meter. Found poor ground as stated above and found the wire coming out of the steering column broken. A few months later i had the same problem as above "works but quits a bit down the road". My fix at the base of the steering column failed. Added a service loop now she's good to go.whistlingdeuce said:I am having a problem with my horn all of a sudden too. I think it is the ghround where the spring rests againist the nut behind the button. Everytime you jump the button with a screwdriver the horn works but with the button in a few miles down the road it stops working again. I have a new switch and will be working or cleaning up the nuit and let you guys know the end result.
