Ray,
The horn button completes the circuit by taking the power to ground. You can
get close to the source of the problem by starting at the horns and working
back - they are easier to reach :). Use a screwdriver or piece of wire to
short each horn to a good ground, after bandaging your head where it hit the
bonnet when the horn went off, try pulling the
wire from the control head you just plugged in and replace it wth the test
wire. When you touch the test wire to ground, you should get a matching
bump on the other side of your head :)
If the first test doesn't produce a beep, make sure you have power at the
horn lead. If you do, my guess is the problem is in the horns.
If the later test does not cause the horns to beep, you probably are
plugging the control lead into the wrong place. If both tests work, then
there is probably a problem at the control head.
When I got my car painted, the horn button got all gunked up so that it
wouldn't make a contact with the ring. I pounded it a few times and it
started working, sort of. I drove into my neighborhood behind an old
Cadilac and when I went over the speed bump, the horn started blasting. The
guy jumped out of his Caddie, I apologized profusely in between honks, he
said "that's all right, I just thought something fell off my car" - shows
ya' where his expectations were.
(sorry for running on --- I really do have to get a job)
