I use car type relays which aren't totally waterproof (few relays are) so mount them somewhere out of the wet (battery area or better: headlamp shell).
2 I've found lying around are:
Ring RLFK 20 12V
Lucas SRB 525
Any car spares shop should have similar. Just ask for 12V single pole, normally open relay.

PS. I use 2 of these to switch headlight beams, takes current from flimsy switches.
PPS The Lucas relay looks fairly waterproof.

Relay should not click until activated by horn button.
Sounds like you've wired the relay coil to the ignition & then wired the horn straight through the switched contacts.
Relay should be wired as follows:
Wire from switched live (ie. wire that becomes live when ignition is
turned
on) to one side of relay coil and one of the switched contacts
(technically
the non moving side of the switch but not too important).
Other side of relay coil goes to horn button. other contact on button
goes
to earth.
Other side of relay switched contact goes to horn. Other terminal on
horn
goes to earth.
When horn button is pressed relay energises & shuts contacts sending
live
feed to horn.
You must use a "normally open" relay.

If you like I'll do a drawing & send it to you.

Tom, Nice pics on the relay placement, but I have a question for you. I am installing a pair of Fiamm horns on my Ambo as the stock unit is
too
weak. I have aquired a Marelli relay to put in line between the
switch
and
the horns. It does work as I hooked it all up before screwing
anything
onto
the bike. One thing I noticed though is that when I turn on the
ignition
key, remember Ambos do not have start buttons, the relay makes a
"click"
sound like it is activated or something. Is this normal? I would
think
it
would make a click when I hit the horn button but why does it click
when
I
turn on the bike? If this is normal that's OK with me just want your opinion. Thanks for your time. Bob Hawkes ----- Original Message ----- From: Tom Bowes <kk-@home.com> To: <Loopfram-@topica.com> Sent: Sunday, July 15, 2001 10:19 PM
