When I purchased my 83 air-cooled Westy, the horn would only work when
turning the steering wheel to certain positions.  I replaced the horn
contact ring on the bottom of the steering wheel and the horn worked
perfectly for several hundred miles.  Then, on a trip to the mountains, the
horn started going off on it's own when turning.

I do hear a grinding noise around the horn ring when turning the steering
wheel.  Did I install the horn ring incorrectly?  Should I not have put
dielectric grease around the ring?

Any ideas would be appreciated.

Thanks,

Marc
