I noticed my steering wheel on my '41 was a bit loose. I tightened it and now I notice my horn button shocks me. I have to be grounded such as resting my left arm on the door sill. It is more of a tingle than a profanity causing shock. What should I check?

I had a '50 Ford that did that. I kept thinking there were bugs on my arm. The wire that runs up the steering column has a low current from the horn relay that is looking for ground. When you push the button, you ground the back side to the steering wheel engaging the relay and causing the horn to honk. There must be a short between the contacts on the back side of the button and the front of the button that you touch with your hand.

Thanks deluxe. I put the horn wire back where it was. I will check it's location. May need a bit of electrical tape.

The horn ring in my 47 used to tingle my arm resting on the window seal. I replaced the horn wire from the engine compartment connection with the stock resistor style wire and it went away.

Thanks for this Henry. It is inexpensive enough to give it a try. Will report back when installed.

The horn relay acts like a little ignition coil. When the button makes contact and pulls the relay, the relay coil is charged. When the button is released, the magnetic field in the relay collapses and the "spark" discharges to the horn button or ring, giving a shock if you hand is on the button. Many manufacturers used a resistance wire from the steering wheel to the relay to prevent the shock. You can do the same with a one ohm resistor in series with the horn button wire.

Thanks Super I am somewhat electrically challenged. Will you give me a dealer and part number for the one ohm resistor and then where to place it in the wiring?

Radio Shack. Walk in and pull it out of their drawer. Or here: http://www.radioshack.com/1-0-ohm-10w-10-wirewound-resistor-2-pack/2710131.html Cut the horn button wire any place between the horn relay and the bottom end of the steering column and insert the resistor.

Thanks Henry. I think even I can handle that!

I got the resistor from Radio Shack and put it in the wire. It works. Thanks, Super and Henry !
