1967 Shelby GT 500 Steering Wheel/Horn Wires
« on: March 31, 2020, 03:54:39 PM »
Good news is that I got the steering wheel off. Bad news is that I have continuity between one wire and the outside horn ring, but I have no continuity on the second wire to anything underneath. Should that wire have continuity with the inside horn ring under wheel? I see that one contact must have fried at some point. The wiring harness horn contacts have one contact where the copper tip is gone, the spring seems to be melted to the post and won't move up or down. There is a burn mark on the outer horn ring under the wheel. But that is the ring that does have continuity to one wire. Should both horn wires under horn button have continuity to the horn rings under the wheel?

Pictures lad, pictures. I'm curious as to what you've gone thru. Don't be stingy.

Here are pictures. Wires horribly mangled by last person in there. Must have been caught under the nut sometime in the past? You can see where the horn pin is burnt off and where the ring has been burned. I only have continuity in one wire to horn ring underneath.

I already answered your continuity question in reply #6 of the previous steering wheel thread. I am not sure if you didn't bother to read or just dismissed the help. If you are going to dismiss or ignore my help then I guess all I can do at this point is wish you well with the resolution of your problem.

I saw that and apologize for your frustration. I was hoping that I was missing something as now the fix as I understand it is to drill a hole from under the horn button into the epoxy and run a a new wire silver soldered to the side of the inside ring that isn't getting power. I was trying to be a non-believer

I guess that since I have one wire giving me continuity to the outer ring and no continuity from the other wire to the inner ring, that I will have to do the drilling and silver solder process.

If I remember right, the yellow wire is power to one contact on the T/S switch and to the wheel. The other contact goes to the horn.
There is no relay in 67 as Ford was trying to save a buck.
So all the horn amperage goes through the contacts and wheel.
If anything goes amiss, zap.
