I just bought a 1975 TR6 and the horn doesn't work. I figured out why but don't know how to fix it. If I ground the steering shaft, under the hood, with a jumper wire to the battery, the horn works. How is the steering shaft supposed to be grounded?
 
There is a flexible braided ground wire that connects both sides of the steering column in the area of the brake booster under your hood. Doubtful that this would be missing, could be broken. Also, there is a ground wire from your harness in the area of the rack and pinion box that affixes to the lube hole bolt in the top of the steering box. Check that as well. Does the horn honk with this rigged ground wire setup when you turn the wheel? Could be the innards of the horn mechanism. Do you have a wiring diagram and a Bentley manual? Need both.

I also had a horn problem too. The braided ground wire was broken and in the steering wheel the brush contact had no contact as well.
I don't know if the situation is the same, compared with my TR4.
 
69TR: My TR had no wires at all in the steering
column. There were no horn button parts either.

I ordered all the parts from TRF and BV but now
I have no idea what part goes where and I am clueless
on where wires might attach.

I rewired my horns up front and they now function
when connected directly to a battery.

Anyone with photos, it would begreatly appreciated.

same here. I bought a timber steering wheel and appropriate boss. I then chucked out the horns fitted (they were of differing types) and bought reconditioned second hand ones(low and high). Still didn't work. After wasting several weekends, I found a fuse in the relay(wot the!) had blown. I fixed this and they worked for a few months. Now I've lost power to the brass ring on the end of the steering column. I can't find the fault.......
Good luck with yours.

Craig

I connected my jumper wire from the battery to the steering shaft near the brake booster and the horn honks with the steering wheel in any position. I did not see any braided ground wires, but the horn worked before I bought the car. The steering column does not protrude through the firewall, just the steering shaft. There is a harness ground wire attached near the rack mount also.
I'll have to check for that braided wire this afternoon. The horn contact in the steering wheel is new.
