I'll never get it dude. took physics then electrical engineering b4 grad school. you are a mess with your definitions. at the same time you have learned a valuable skill. people are lame and always want vape instead of fixing things.
floating sucks and you never want to do it. you need to isolate everything from the frame.
your work is excellent. don't misunderstand me. all my bikes are wired dc. I'm not a moped guy but I make my own baja boxes. done many 2t legal dirt bike conversions. that's why I see what you did. I do it myself. some of you terminology is flat out wrong. you can only float dc voltage. it is impossible to get all the ac out. dc is linear but it moves about, it floats. I say you did a amazing repair and you have a valuable skill. I say you reassigned the ground point from the frame to the rectifier and took a half wave grounded ac stator and converted it to full wave ungrounded dc . that is not lame at all.
