I'm looking into changing the original (wimpy) horn to one that will be more effective in getting attention. I was planning on using the same mounting and wiring without a relay as I see the horn fuse is rated at 25A. I assume this rating also applies to the wiring and on/off button for the horn but am baffled by the note in the user's manual which describes the fuse as 25A, Load Shedding. Can anyone tell me what load shedding means and how this impacts the fuse rating.
