Fiamm Freeway Blaster low = 9 amps(spec sheet). High shows 6 amps
A 10 amp fuse will not handle TS, Brake and Horn.
I suggest you replace that fuse, it may have issues.
You could test the horn at the starter relay battery cable and frame Ground to see if said horns are good.
Relay --yes you need a relay and a 20 amp fuse feeding that horn.
The VTX horn wires are great for triggering the relay..
