Jesse,
I just looked at Guzziology tonight and was able to connect the Fiamms via
relay and the whole thing works great now. I even used an original Marelli
relay. Thanks, Bob

Did you try it without the relay ? Try the horn at the battery to make
sure it is working. Make sure the bracket is making a good ground at
both ends. Star type lockwashers between the frame and bracket with a
little Anti Sieze help here. You may have to run a heavier gage wire to
the relay contact from the battery . Use a 20 amp circuit breaker at the
battery end . 14 or 12 gage wire should be fine. Use the original 2
wires from the Guzzi horn to activate the relay coil. Make sureyou are
getting voltage at the relay coil when you push the horn switch.

Hey all you electrical gurus,
I want to replace the stock two prong Ambo horn with a Fiamm one prong
horn.
I have a hot wire and a switch wire. The Fiamm seems to be grounded
just by
the hardware mount. I bought a standard 12 volt relay with 4 prongs

but

no
matter how I wire the thing I can't get the Faimm to sound. Any
suggestions
(other than sticking to the weak stock horn)? Thanks, Bob

I'd make sure the horn was good first. Run a wire directly from the +
side of the battery to your one prong. the horn should sound.

If it doesn't, remove the horn and touch the mounting bolt to the
negative
terminal of the battery and the same jumper wire you had before from the
battery + to the terminal of the horn.

If it still doesn't sound, you have a bad horn.

If it DOES sound, it means that you don't have a good ground for the
horn
and you need to either run the other wire (from the original horn) to
the
bolt on the horn, or clean up the frame mount to give a good ground.

Now you knopdw that you have a good horn, and a good ground.

If it STILL doesn't work, you either have a bad relay or a bad switch.

If you hold the hot horn wire from the switch to a 12v bulb and the
other
part of the bulb to ground, the lamp should light when you push the horn
button. If it doesn't, you have a bad switch. If it does, then you
have
a bad relay..

There will be a quiz at the end of the hour...

Good luck!
