well this thread has turned into a total shitshow, this el pollo is just blathering crazy nonsense. I cant figure out what the hell he is on about.
are you trying to run LED lights?
the coil you have is not a floated ground coil, its dual tapped. I just recently started experimenting with these and the china regulators designed for them, basically its like two coils in one, but they are both grounded. you can't hook them up to the two AC poles of the rectifier the way you probably think you can.
they are meant to be run with a dual-mode wiring schematic like this one:
the white and yellow wires are the two 'taps' on the lighting coil. one directly drives the headlight and the other one gets rectified to a battery. this way you have plenty of power for a ripping headlight and you can charge a battery without overpowering it.
its what was called a 'balanced' system, works great (reliable) with fewer components to fail... back in the day regulators were expensive and unreliable... but they don't work well with modified engines turning higher rpms or modifications to the electrical system.
if you post up your desired lighting/equipment and loads i can draw you a schematic, i haven't tried the capacitors yet, bought some for a project and ended up going with an SLA instead.
