more moped army nonsense. you cant float a stator period. what is wrong with the people here. the only thing you can do with a stator is change where its grounded.
6 to 12 what's wrong with using ohms law to do it. change in load will change the voltage. what you need is modern bulbs, not a different stator.
the lighting coil has nothing to do with ignition. it has its own dedicated stator.
that crappy diagram does not show much. seems to be a recurrent problem here. you need to test the stator and see how the thing is wired yourself. once you know how the stator is wired then you can order the right type of modern r/r.
one hint. the tail light runs off a tap in the stator. it is not used in your conversion.
