Hello, how can change the cable in the handlebar which conect the knob in the steering wheel to the horn? Ask Wolfgang
Do you have a picture of what you are working on, Wolfgang? I'm not sure exactly what you are needing to do. Maybe connect up your horn button to the wire?
Hello Zig, the wire that comes out of the handlebar, the tube where the Steering wheel sit on, is this power or ground? wolfgang
It is a ground. When you push the horn button, it grounds on the steering shaft. There is a contact that goes behind the steering wheel to the upper bearing, which has a wire that runs down the column and out through the hole halfway down. This wire grounds the relay, sending 12v. out to the horn.

Horn Wire Wokri ; The " handlebar " tube is called the Steering Column Mast Jacket . The wire you're looking at , runs up inside it and is connected to the upper bushing , the outer face of this bushing is a copper ring that occasionally needs polishing *very* carefully with metal polish but never , EVER sand paper , crocus cloth , steel wool or other abrasives . If you look closely as the outside of the Mast Jacket just below the upper bushing , there's some small tabs and you can use a thin flat bladed screw driver and a mallet to gently knock it up and out to replace the old wire that has bare spots that cause the horn to toot without your permission . Me , I'm too lazy so I unplugged the wire where it comes out at the bottom and connected a long thin steel wire to it and fished that through some 1/8" or so (? 5 MM ?) plastic loom covering (like heat shrink tubing) then I *gently* and laboriously pulled the steel wire while I guided the plastic loom up the Mast Jacket via the small oblong hole near the bottom . Once I had however many inches of loom slid up inside until I left it bump against the bottom of the upper bushing , I trimmed it , removed the steel fishing wire and plugged it back in , 25 years later when I sold the truck it was still working fine . I strongly suggest adding a relay to the horn circuit so the horn button's contacts only carry the relay's 1/4 ampere current and not the Horn's 10 ampere draw . I hope my ' Farm Fix ' might give you some idea of how to proceed and not 0ffend any others here . If you shatter that upper bushing trying to remove it past the 50 + year of accumulated rust , dirt and paint , you'll be *very* upset and wishing you'd tried my fix first . Best of luck , let us know how it all worked out .
