i had a black wire with yellow stripe fall off of the neg term and it did start my bike for a short bit but i ignored it and it blew my fusebox. dont ignore, reground and make sure it doesnt come off. i went riding and everything was fine as far as i knew, till i turned her off and came back to a bike that wouldnt turn over. my acc wire is orange and gauged a bit bigger than most of the rest. what yr is this bike we're talking about?
