A puzzle: toot the horn and get a shock!

[ojxxx]

This is a mystery, you toot the horn and it'll give you a shock. I put this together last year, the owner wanted this steering wheel and had an adapter but didn't have stuff for the horn because the telescoping wheel. I machined this paddle assembly and it works great, gives a ground just like the factory. Except it'll give you a shock if you touch metal and the paddle. Car don't even have to be running, key 'Off' and it'll give you a little zing. Shelby had the horns direct, the hirn button supplied ground, I even isolated the horn circuit with a relay, the ground triggers the relay not the horn.

solve the problem and win a Prize!
I'll have the car here for a couple days, suggest away and I'll twist the wrenches.

Bad Ground?

This sounds like the electricity that should be going to ground directly when the horn contacts are closed is meeting resistance and finding another path through the person touching the horn ring. I don't recall exactly how the "downstream" side of the horn ring contact goes to ground, but I would track that electric path out and make sure that there are no impediments to any electrical connectors, even where the connector is simply two things bolted together.

Good luck!

Well, there it is! I thought I had started a thread about this problem and I looked in the wrong section.
I hadn't read his suggestion, the car left my shop after I posted last in that thread. The horn paddles are insulated until they make contact. I know what he is talking about but the horn loads aren't on the horn paddle circuit, the paddles ground a 60milliamp relay coil.

I am starting to remember what all I did to try and solve the this, I'm going to dig up my notes from when I worked on it and see what they have to say. I remember I had an engineer looking at it too, the thing is its all right there in front of us and we should be able to point at a widget and say 'thats the pisser, its backwards' and be done with it.
The car is just back for routine tune up, I'll keep it for a few days.
