Steering Wheel screw SPARKS?

[Dnrice]

So, I was going to put in the bow tie center for the steering wheel. I believe it is original because the steering wheel looks really beat up. As, I was unscrewing the screws that hold the metal circle which holds the center piece, one screw had sparks when I touched it with the screw driver. No shock but I quickly put the screws back like they were.
Anybody know why there were sparks? Thanks

If you didn't hear the horn I'd say you have something else to fix as well. The horn button retainer is part of the horn switch assembly. Always hot it grounds there to sound the horn.

mine did the same when i put a grant wheel on it, it turned out i had a ground loose under the dash. no biggie to fix

I don't think I have a horn button. I guess it was suppose to be there where screw is.

Check the horns and make sure the green wires are connected if there is no sound.

I've always found sparks to be usual when I'm screwing with my horn, so I just disconnect the battery so it doesn't annoy me

I looked at a diagram of "Steering" in LMC. I am missing the horn button bushing, the washer which goes under the horn button cup. Also, the gasket cap which goes under the horn button cap.
