I have been going round and round with the horn on my Deuce. When operated it sounds like I have half a horn, and my air pressure is over 100psi. I have done an archive search and couldn't find a problem quite like this. So I replaced the Solenoid thinking that was the problem, and checked the connections at the Solenoid, and replaced one connector, checked the solenoid wire to the wire in the steering column, and to the short wire on the horn button. I also checked the ground to the horn button (spring) and steering wheel and cleaned everything there. When the ignition lever is turned on, engine not running, I have a nice loud click when I press the horn button. Get the truck running and air pressure up...……..and my horn still sounds like a mouse. I also did a soapy water check on all the air fittings leading to the horn, and no leaks. This problem started suddenly about 2 weeks ago. Can the trumpets on the horn assembly go bad? It's probably the original horn assembly from 1971/72. Thanks!!
