Keep us informed..
My educated guess is the horn caused your problem not being wired through a relay. Modern electrics and CAN BUS are fragile.
The soundbomb mini is advertised at pulling 5 amps, and the bigger one is said to be 20 amps.
Apparently on the KTM 1190, hooking the mini straight to the harness causes a fault because the bike only expects a 1 amp draw from the horn.
Looking at our wiring diagram, it looks like the horn is wired directly to the dash, without a fuse in between.
srikz, check your fuses first. Hopefully it is just a blown fuse. Whenever you get it fixed, you should put a relay on that horn.
