Horn
I'll get the horn working and after the couple months driving around Town--
it slowly will only chirp. Do they require that much attention, or what. It's not a Model A if the horn don't work right -- and yes, it's been rebuilted/oiled. |

Re: Horn
Your generator needs to be charging to get a good horn sound. Otherwise, loosen the adjuster screw one or two clicks on the back of your horn and see if that helps.

Re: Horn
Guten Morgen,
it is also important that the copper collector and the motor brushes are free of grease and smooth.

Re: Horn
I use sewing machine oil to oil my horn. The outside temperature plays a part in the horn efficiency. If I know I'm going to be using it: I back off the screw, press the button and spin the motor to warm up and thin the oil. I then retune it by adjusting the screw.

Re: Horn
My horn has stopped working, all of the above suggestions have been accomplished. In the dark I noticed occasional small sparks behind the horn button when pushed and a slight sound from the horn. Suggestions?

Re: Horn
If you mean, by horn button, the button in the middle of the steering wheel, sounds like it’s rusty, or corroded underneath there. I have just held the horn button down, and rotated it with the palm of my hand to try and clean it, which helped. I am not sure how you could see sparks from there though?

Re: Horn
On my A, I added a ground wire for all six of the lights, the horn, and finally the engine to the frame. Grounds or lack there of, can be real gremlins.
