I've read some posts on this especially the one by Entropy in 2015.
I have noted that the horn switch on my bike did not function at a key point in time (some #### was pulling out of a blind junction).
Having purchased a Denali Soundbomb mini, it seems on swapping out the corroded crappy OEM horn that the switch itself is faulty and doesn't seem to be connecting well.
Can one of you sharp folks out there tell me if it is possible (or even wise) to disassemble the switch gear to fix the switch? I don't fancy paying £157 on World of Triumph for a new one, and don't trust the cheaper used examples on e-bay.
