You have to look into all that.. You should get a schematic to the motor.. To charge a battery you need a voltage regulator or a rectifier of some sorts.. You gotta have a way, for juice to flow out of the motor, to a one way voltage feeler thing, to the battery..
The battery dips below a certain voltage, the motor charges it.. When the motor is shut off... voltage from the battery goes to the rectifier, and STOPS dead in it's tracks, as it only allows juice to flow one way..
It doesn't burn stuff up, and run your battery dead when the engine isn't running..
if you're getting two different voltage readings, and it's wavy, try spinning the rpms up on the motor some.. The faster they spin the more power they make.. It's probably just a standard lighting coil, one line has two coils inline making twice the voltage, one coil is separate running one wire with only half the power..
Green is pretty well always the engine kill.. ground that to the motor or frame and it shorts out the ignition coil and shuts the motor off..
