On a 12 volt 2 wire stator, connect the green and yellow wire, along with the white and green wire, to both yellow AC wires of the regulator. Then, connect the red (positive) and black (negative) wires to your motorcycle’s wiring. On a POSITIVE ground vehicle, the red goes on the ground, and the black to the battery’s negative terminal. On a NEGATIVE ground vehicle, the black wire goes on the ground, and the red wire goes to the battery’s positive terminal. Figure 1

If your stator is a 6 volt 3 wire one, join the green and black wire to the green and yellow one to convert the power to 12 volt. Then connect those wires to a yellow AC wire, and connect the stator’s green and white wire to the other yellow AC wire. Now, connect the red (positive) and black (negative) wires to your vehicle’s wiring according to the 12 volt example above. REMEMBER TO CHANGE YOUR LIGHT BULBS, COILS AND BATTERY TO 12 VOLTS!

If you wish to reduce your motorcycle’s wiring, you can install this box to take out the rectifier and Zener diode. The built-in capacitor allows your bike to start easily and allows you to get rid of the battery if used with a points ignition. You can still keep your battery, but you can sleep tight, knowing that your vehicle will still start no matter if your battery is dead or low. You can use it alongside 2 and 3 wire alternator, or to convert 6V alternators to 12V by connecting any of the 3 wires of the alternator to this unit and change your light bulbs to 12V.

*Note that this unit does contain a capacitor unlike some other products listed on eBay. **Because single and three phase boxes are very sensitive, you will need to put 5000 ohm spark plug caps. Otherwise, they will be overloaded.
