derbi gpr50 wiring help

[steeeeeve]

hi fellas.
i'm a bit stumped and could use a little help[ on wiring my Yerbi for lights.
i got a derbi/ysr a while back for track use, but the track has shut down and i'm trying to rig it with lights.
most of the electronics have been stripped so i'm starting pretty much from scratch.
what i do know is i have a yellow wire dangling loose from the stator that reads 20 volts AC while the motor is running.
now where do go from there? i bought a 12v battery and a 12v cheap chinese regulator/recifier, but with only one hot wire dangling loose i'm not sure how to wire it up.
here's a pic of what's coming out of the stator.
