2018 Honda NC750XD ... So I buy a plug and play Denali Mini Soundblaster horn. Only problem is it blows the fuse. Not just the fuse to the horn but the fuse to nearly half of the bike including display. The dealer says the Denali draws too much current for the 7.5amp fuse? Also, I was looking at installing an accessory 12v plug and it takes a special sub-harness as well as special harness plug on the 12v socket. Now I need to install a battery tender plug to keep the battery charged in the garage. What kind of electrical system have I gotten myself into? Can I install the battery tender cable directly to the battery?
