I am having trouble with the horn on my 67 rs. Everything is fine up to the steering wheel. I can jumper across from the horn pin to the steering shaft and the horn works fine. However, there is high resistance between where the horn button contacts and the steering shaft. It seems that there is an insulator between the splines on the steering wheel and the area that the button contacts.
Question: Is there a jumper wire of some sort that connects between the (horn button) contact area and the shaft?
It's the paint. I had the steering wheel restored and the black finish covered the base of the steering wheel hub. When I bolted the chrome spokes to the wheel, the paint prevented current from reaching the splined center hub.
