Grant--
I had exactly the same problem and the cause was an abraded wire running
from the horn button through the steering column (I had replaced the
wiring harness as part of a frame off restoration). Have you recently
disassembled/reassembled your steering column or the wiring channel
underneath the column?
Regardless, remove the horn button and the steering wheel and look
cuts/breaks in the wiring insulation. My problem was caused by a sharp
rim inside the column. I ended up splitting a piece of thin vacuum hose
(1/4-3/8 inch diameter) and pressed it on to cover up the rim. Another
alternative would be to somehow "armor" the horn wire through the
column. That can be problematic as there is limited space in the
column, especially where the wire exits.
An annoying situation to be sure. Good luck with your repair.

Subject: [6pack] Horn and Steering column
Dear List,
I've got a strange problem (well, maybe not that strange given Lucas
electronics). When I turn the steering wheel my horn sounds. It was
intermittent at first but now it's pretty constant. It effects both the
left and right horns (I tried disconnecting each). If I even shake the
steering column, under the hood, I can hear a kind of microphonic noise
from the horns. I removed the horn honking mechanism from the steering
wheel entirely so I'm guessing this is a short someplace? I don't know
where to begin looking, and the wiring to the horns goes through parts
of the front end of the car that are difficult to get access to. Has
this happened to anyone else? Any easy fixes or do I have to go through
the wiring harness (yikes)?
Best,
Grant Kester
