before you go and replace the horn...
check the surface of the horn near where the mount bolt is.
If there is a second screw that protrudes put doesn't look like it
mounts anything, or by viewing you'd think it mounted
something internal....
this is an adjustment screw. Record the present position of the screw.
(slot angle/position) give it a good tweek... max of two full turns in both
directions from the initial position.
Disconnect the working horn, have a friend push and hold
the horn button while you fiddle with this screw... it may just start working
again.
This screw is basically a 'stop' for the little vibrating disc within the horn.
With age, normally very little use, metal fatque, and rust, it just doesn't
vibrate correctly
move the 'home position' of the stop and you may just get it working again.

Subject: Horn Question
OK, I've got two horns (which seems to be standard), and only the first is
working. No problem here...if I can't replace a horn, I probably shouldn't
own the car. My question is, since I've never heard the system working
properly, is there a tonal difference in the two? Do I need to properly
identify which horn I am replacing in order to rectify this? Curiosity as
much as anything else....and deciding where to place this on my to-do
list....somewhere behind "leaks at every conceivable point!

72 Spitfire...great shape if you discount the fact that it leaks more than
my four month old daughter!
