You know I've played around with the white wire out of my 48cc engine, it's just a parallel connection to the blue wire from what I can see.
Without any other load other than the magneto, I see 28 to 50 volts AC off of it, and I've been trying out various 110 volt AC to 5 volt DC switching power 'wall warts' connected to the white wire and grounded to the engine. I found that the wall wart will charge one of my USB rechargeable flashing/steady LED bike headlights, without causing the engine to stumble or run crappy at low RPMs. It might succeed as a charge maintainer, the magneto's current overhead through the white wire maybe more than adequate.
I've noticed that at lower RPM the wallwart goes dead, so maybe it's not using any current below a certain voltage out of the magneto. I need to test this more as a long term project to see if the magneto is up to sourcing a little extra current while charging various small lights and cellphones as a steady diet.
