1963 300. All parts of the horn system work just fine.....relay, wiring, horns et.al
. What doesn't work is the ground coming up the steering column through its iron pipe. At straight ahead (when you most feel the need to honk) there is no ground at the steel steering shaft. Rotate the wheel a few degrees, and ground starts again. This situation has nothing to do with the steering wheel or the turn signal switch, or the horn ring or anything other than some mysterious source of ground going away at straight ahead and returning at turns. I have replicated this ground dying
at straight ahead without the steering wheel attached using a test lamp. Anybody know the source of horn ground to the steering shaft?
