The Horn
 

My horn worked, but not as good as others I have heard. Most of the time it sounded lame at idle, or wouldn't work until I went for a drive. Today, it wouldn't work at all, before I decided to take it apart, I sprayed it with electrical contact cleaner, what an amazing difference, it never worked this well since I owned the car.

I just held fine crocus cloth against the commutator on my friend's horn, and in a few seconds it started to speed up and sound like it should. Oil the two felts, and keep the commutator clean, and the horn usually works quite well. Also the horn button contacts may have corrosion if the car has been out of use for years.

Yes the electrical connection can get corroded. I've put kroil into the bearings, and that makes a difference as well.

I put a drop or two of light oil on the pads now and then - usually when it starts to sound sick. I spray a tiny amount of carburetor cleaner on a rag and wipe the commutator. Presto, it's done. Works every time.:D
