Jery-
I had the same problem on my '75 when I bought it 3 years ago. I traced the
problem down to the horn button itself,
and dissected it to see if I could fix it. My button was indeed the culprit,
I found that the button uses a conical coil spring
of some copper/phosphor bronze material. The spring has a contact in the
center for shorting the housing to ground. This had broken off, and was not
doing it's job. Also there is a plastic piece in there somewhere, (been a
while since I did this) that
was broken due to age/brittleness. Basically I just soldered a square piece
of brass sheet metal on top of the broken coil spring that would allow the
horn to short to ground. My advice would be to take a look and see if you
can fix it, if it isn't too beat up, you may be able to salvage it.
Good luck!
