Steering column/horn switch ground?
89 F-250 460
Horn only works when key is off, figured out that the switch is not getting a ground, except when the key is off and it grounds through the column lock.
my question is, how does the steering shaft get its ground? The ground wire from the horn switch simply clips into one of the threaded holes in the steering wheel 'hub', but this is not grounded and i can not figure out how it should get its ground. I assume the shaft should be grounded?
Black wires = horn/CC ground to steering wheel 'hub'
There is no clock spring in the column, only the two spring loaded contacts at 2:00 make contact with the wheel.
Anyone run into this problem? Ideas? Suggestions?
Thanks in advance

IIRC the horns them selves are grounded on your trucks body (at least mine are for a 95) and the horn buttons are essentially a switch from battery to horn (with inline fuse) now you MIGHT have a slightly different set up depending on the steering wheel and the fact you don't have air bag, BUT horns should more or less be set up so its button (horn switch) is just that a switch, press it and its on release and its off...
again im not sure how much different your set up may be based on your truck and steering wheel but horns generally are grounded direct to the body for the most part...least from what i have observed and understand by looking and reading my repair books...
also I would suggest contacting subford as he has diagrams that may help...IIRC that is...hopefully subford can chime in soon and correct me if im wrong!

Yeah the shaft is grounded where it connects at the frame.
Though Im having the same issues, and Ive now gone through 3 different steering wheel horn/cruise pieces.
Its driving me nuts, Ive even checked for voltage while driving. (So unsafe, I know).
Voltage goes in, but doesnt seem to ground out, unless key is off.
But the worst, is my cruise isnt working either

I had that problem once, do not remember the year of the truck or if it might have been a car. What I did was take a wire and crimped two ring connectors on each end and put it around the flex joint at the bolts that bolt the flex joint to the shaft and the steering box.

There are two carbon spring loaded contacts which are part of the
turn signal/hazard switch. They make contact with the cam
ring you posted.
One contact (Yellow/Light Blue wire) is for the horn relay primary coil.
When the horn button is pressed, this wire is grounded and the relay
is energized.
The other contact (Black wire is the ground path for both the horn
relay and ground for the cruise control switches.
The two wires are part of the turn signal hazard switch and exit
out of the turn signal hazards switch connector pictured below.
