Topic: Horn wire repair


682bear    -- 11-30-2023 @ 11:28 AM
  I've discovered that the wire that goes into the bottom of the steering box on my '40 Fordor is in pretty poor condition.

Right where it bends to go into the box, the insulation has broken off and left the wire bare... if I move it with my hand and touch the side of the hole with it, the horn blows...

Yeah... that scared the cr*p out of me...

Anyway... what is the best way to repair this? I would guess that any repair would include pulling the wire out of the column at least partway... how difficult is it to run the wire back through?

My thoughts are to disconnect the wire at the horn button, attach a cord to it, then pull it out the bottom, pulling the cord through with it. Disconnect the cord, slide a length of shrink wrap over the wire down to the bare spot, shrink it on, then use the cord to pull the wire back through...

...but I don't know how easily that would work...

Any ideas?

Thanks-Bear

  I have done this a couple of times-it's not a bad job.

You can buy a repro steering column wire with the steel end for the horn button on one end and the bullet connector on the other, all ready to be installed:

The first time, there was no existing horn wire. I removed the horn button and pushed the new wire down in-it hung up a few times but, as the wire is fairly stiff and has a bullet connector on the end, it came through the hole in the bottom of the gearbox with no problem.

When I changed it last year, I did the same thing.

As long as there are no obstructions in the steering shaft/tube is shouldn't be a problem.

That being said, using the old wire as a pull string is a very good idea.
