Grounding a steering column

Grounding a steering column - 06/19/22 11:16 PM

The horn on my Lil Red Express does not work. According to the FSM the steering column grounding clip could be missing, resulting in a loss of ground to the horn switch. Where exactly is the grounding clip? Assuming it's just grounded to the firewall.

I know on the older stuff that the rubber isolator for the bearing in the column has a staple in it, that supplied the ground for the horn.

I do not know if that was still done by the later seventies though?

Don't know Little red specific, but a lot of Mopar columns had a steel spring clip the clipped over the plastic bushing at the top of the column mount that was used as a ground (usually on just one side of the column or the other). The steel clip fit between the column support and the column itself, over (or around if you will) the plastic spacer in the column collapse part of the top column mounting. If that was broken, or is missing, the column could loose its ground.

i have scrapped several mid to late 70's newyorkers over the years, and kept the tilt-telescope columns.
all of those had a bare, "ribbon" type of ground running from the column at the mount bracket to the dash frame.
that "ribbon" is approximately 2 1/2" or so long, with eyelets at both ends. one eyelet is 5/16" to fit the column mount bolt, while the other is maybe 3/16" [?] to fit a #10[?] screw.
i don't know if this helps or not.

Thanks for the replies. I actually fixed it. I grounded the steering column to the dash and managed to get a crackling sound out of the horn. After cleaning all connections, a bit better but still nothing. I haven't run the truck for a year so the battery was still not fully charged. Decided to pack it in for the night and started the truck up to let it run a bit and tried the horn one last time. Yeah, apparently horns needs a full 12 volts to work, at least this one...
