Getting ready to get the annual safety inspection done and of all the things to fail on this bike, it's the horn.
I unmounted the horn itself, popped it on another bike, works just fine. Put it back on, no joy.
Visually inspected the innards of the LH joystick/switchgroup. Didn't see anything wrong.
Checked each of the fuses in the tail section, all look good. All other electrical systems are working fine.
Any suggestions of what to check next? I was looking through the service manual for a horn relay or some such but wasn't finding anything.

Test for 12v at the horn while pressing the button with a voltmeter. No power there and it’s upstream, likely the button itself

There is no relay.

Just had the switch cluster replaced under warranty on my Tuono, same problem the switch contacts are exposed to the elements and oxidise. Mine was intermittent though.
