Hi Will-

Take a look at a TR4 wiring diagram if you have one handy - the horns do
ground through the horn button - eventually via the steering column/steering
rack.  If you want to keep experimenting, take your alligator clips and ground
the metal steering column inside the engine bay, just before the uppermost
rubber coupling.  With it grounded, try your horn button - if it toots, you
are loosing ground through the column as it goes to the rack - work your way
down if needed to find the fault.  If it doesn't work, you are losing ground
possibly at the horn ring, you could find where the purple/black wire goes
into the steering column and check there first, if good its something going on
with the horn ring/horn pencil/horn button.

ps.  Nice to meet you at the Mitty! (red TR4..)
