Help with Horn Contact
I've been working on my turn signal switch and additionally my horn. Its the horn I'm confronted with. I have the horn contact under the steering wheel powered up and grounding it clicks the horn relay. I have an aftermarket steering wheel. It has a wire coming up from the horn contact plate that clips into the horn button. The horn contact makes a good connection with the contact plate. If I ground the wire going to the horn switch, I also click the horn relay.
My problem is that the steering shaft isn't grounded. My horn button wants an additional connection to ground but there is none available through the steering shaft. How does the factory horn work with the single contact and no ground through the steering shaft?

Thanks for the tips guys. I don't have a rag joint but was able to confirm that my steering U-joint is the culprit. In order to make life difficult the downhill side of the joint has no bolt to put a contact under. I'm thinking I will take a piece of stainless tig wire and attach one end under the clamp bolt, bend it in a zig-zag, and clamp it to the shaft on the other end. Won't be pretty but should work.
