Was poking around Alibaba and found a description I did not understand. Magneto Primary Voltage Generator "Magneto". This coil provides voltage for spark, a trickle charge, and trigger for CDI igniter coil unit. Now i know what the Mag is and what it does but I am assuming the "trickle Charge" they are speaking of would be the white wire. What would it take to use the white wire to charge a 6V Battery? As i understand things the white wire puts out roughly 7 volts and 3 watts. that would seem to be enough voltage to keep a 6v charged. I also believe there is AC not DC at the wire how much of an issue would that make?
