The horn that the MoCo replaced on my 07 UC is going bad again. With 105 years of experience, you would think they could build a weather proof horn. Is it just me?

 

Prolly still under warrente have it checked by the dealership maybe!?

 

They replaced it under warranty, and will again......... In another year when the warranty is gone, I will buy a better horn.

 

Check the wiring all the way to the switch inside the housing on your handlebars. I had a similar problem and it turned out to be an intermittent short that fried the horn. Fixed wire, fixed problem!
