How to Convert AC to DC Wiring on a Motorcycle?

[IslaLee]

Replace the original rectifier with a DC rectifier (four-wire or five-wire). Disconnect the center tap of the original generator coil, which is the white (or yellow) wire (be careful not to break the enameled wire), and insulate it properly for disuse. Disconnect the grounded end of the original generator coil and connect it to the previously disconnected white (or yellow) wire, then insulate it properly. If the rectifier is four-wire, connect as follows: the green wire to ground, the red wire to the battery fuse, and the other two wires to the two output wires of the generator coil respectively. If the rectifier is five-wire, refer to the fourth step above and connect the black wire to the red wire or the black wire on the motorcycle.
