Horn re-wiring help

[Southtowns27]

Well, the horn on our 1950 1/2 ton decided to start blowing itself. Whenever you'd turn the steering wheel several turns, like when trying to park, the horn would turn itself on and maybe turn off after some period of time... I've since disconnected the power to it, but I really need to fix it. Can someone please explain how the wiring in the steering column works and how to repair/replace it? Thanks!!!

The wire in the column provides the ground through the button. Seems to me with the problem you discribes you probably have some insulation worn off the wire that is some how making contact with something when you crank the wheel. The horn button presses against a ring connected to the wire to provide ground.

There is a wire with a connector on it coming out of the steering box. thie wire likely needs to be replaced, To do this attach the new wire to the old on at the steering wheel, ad use the old wire to pull the new lenght through the column. Then reattach the new wire to the original connections like you found the old one. Unless of course trucks are different than the cars.

Yup... Greg pretty much nailed it.
