So the horn doesn't work on my 65 300. Last weekend, I took off the steering wheel and checked all the points. If I take the horn cable to touch the turn signal stalk or gear selector, the horn works, so there is some sort of ground in the column.
I've tried to locate a ground strap, but couldn't find one. I even tried to tap one in, but to no avail. Took a multimeter and found that the steering shaft would only allow 3-4 volts to travel. Now here is the weird part. If I unbolt the column from the dash and push it to 7 o'clock, voltage goes to normal at 12V, and the horn works as it should, move it back and it drops to 3-4 again. I inspected the wires coming out of the column, and tried to move them around thinking the ground could be loose, but that doesn't help.
As a temp fix I've wrapped copper around the steering shaft and grounded at the turn signal grounding plate, but would like a more permanent solution.
Any ideas? Or is this something where I have to take the entire column out to inspect/rebuild?
