67 Horn ground circuit help
Can anyone provide a description or pictures of how the horn ground circuit should be wired within the steering wheel?
My horn doesn't work. I have taken off the steering wheel and replaced the single contact brush mounted into the plastic turn signal switch plate within the column. When I ground that contact the horn goes off. No problems there.
I then noticed that there is no conduit connecting the metal plate mounted on top of the steering wheel (where you press down on the horn centercap button to ground the circuit) with that mounted on the bottom (where the contact brush rubs). I see a vacant hole in the hub of the steering wheel that looks like it should have a wire running through it to connect the 2 plates, but I dont see where you would secure the wire (no mounting clips or attachement points).
Am I missing a wire or something?
Thanks,
Dcubedus

Dcubedus, I just ran in to this same problem this week. I changed steering wheels and my horn worked fine. Then I changed steering columns and it would not work. I finally found out it was not grounding enough. To fix this I had to run a new ground wire around my new rag joint, from the steering gear box end of the rag joint to the column end of the rag joint and now the column is grounded good enough for my Horn to work. I just unbolted one bolt from the new rag joint and used 2 #12 stranded wires with the insulation on and used terminals ends big enough to go over the bolt. The whole wire length with terminal ends included is about 3in. long. This worked for me. Good luck and let us know how it turns out. Charles

Thanks Charles. I did check the column and it is adequately grounded. I can physically jump the contact switch to the steering column and the horn works. I just want to know how the 2 plates within the actual steering wheel are supposed to be connected. Can you look at your new wheel for me? Possible just pop the horn button off and take a pic?

Dcubedus, I took some pictures of the horn button removed but I seem to be having some kind of problem down loading them into the computer tonight so I guess tonight I wont have pictures for you. My horn button is just held in with a tight O-ring seal and it has a wire from it going into the center hub. It has been a while since I put it in and I cant remember what it connects to in side. I have a Laccara steering wheel and the supplied hub base to mount it did not work on my truck so I got a grant 3 hole adapter and made my steering wheel 5 hole mount work on it. The grant adapter has a smooth metalic base plate on it that the spring loaded steering column electrical fitting rides against. I assume this gives connection for the horn button to ground out against but I have never tried to measure voltage on it as my problem was ground related. Sorry I couldnt be of more help. Charles

No problem Charles. I do appreciate the effort
I didnt realize that you had an aftermarket steering wheel though. I am pretty sure that I must connect the two plates together but just don't how the factory did it.
Does anyone out there have a 67-70 stock steering wheel (with a functioning horn) that they can snap a picture of (with the horn button removed)?
