Okay I drew a few different wiring scenarios that I will share here once I'm confident. I understand how "floating" the lighting coil works now. Just experimenting with other crap.
I'm really hoping that once I'm done with all this I can dumb it down so much, anyone reading this thread will come out with a good understanding.
There will be two electrical circuits on the moped.
One for all the ignition crap
One for all the accessories
One of those will be AC and the other will be DC.
I was trying to mess around and instead of "floating" the lighting coil, use the frame as ground and ground my lights but I can't think of how that would work.
