I'm fixing my horn on my '65 Ghia. I've troubleshooted by horn (problems included poor connection on the jumper to the steering box and a bad relay), and I'm 99% of the way to getting the horn to beep correctly when I press the horn button.
The last problem I'm facing is that the chrome horn lever (the semi- circle thing) doesn't make a good electrical connection from the ground wire (that comes up through the center of the steering column and screws into the ring near the center of the lever) through to the copper donut on the underside of the lever. In other words, the copper donut is NOT grounded. I've checked. (But I can touch the ground wire to the column and the horn beeps.) I think the only problem left is that the chrome paint on the lever is a bad conductor.
So am I doing something wrong? I am surprised that anyone expected electricity to pass through the chrome lever. Maybe there is supposed to be some type of conductor/jumper that is supposed to go between the screw that holds the ground wire and the copper donut?
