here is a case where you ask the wrong quesion. you are looking at the problem all wrong because which way you wire depends on how your stator is wired. what you should be asking is what way is easier.
ac to rectifier then regulator, full wave dc ungrounded stator. scoot r/r.
ac clipper regulator, then rectifier, trail tech, blaster, kdx or any ac dirt bike 12v 2 wire ac clipper, half wave grounded stator. you must change to all led's to make 6 to 12 work. simple and no need to remove the flywheel. no need to rewire the stator. remember do not use the - terminal at the rectifier. it is n/c and not grounded to the frame. - voltage is the half of the wave that gets wasted. but wait the scoot r/r comes in half wave flavor. that means ac then rec then reg and ground at the frame.
do yo know what capacitor you need?
