Before attempting to use all circuits here regarding voltage regulator for motorcycles, let us first differentiate the two system. Not all machine are the same especially with the design of the voltage regulator. There are single phase system that uses half and full wave charging system, and three phase system that uses half wave system..By looking at this block diagrams, you will be able to determine what system your bike uses by following the connection. FJPGVS6ZRZW7



First and foremost, the single phase, the picture above illustrates a single system half wave regulation, you can see that the one end of the stator is connected to ground, via earth ground, the coil has also a center tap on the winding for your headlight and the output will also be regulated by the voltage regulator..this kind of regulator is a single phase half wave system, if the end of the winding is no where connected to ground then the system will be a full wave.







Next the 3 phase system.

This system can easily be distinguished by the three yellow wire, sometimes three white depends on the brand of the bike. when you see one, then its a three phase already. Note that there is no wire for the lighting coil coming out from the stator, this means that the headlight is directly connected to your battery, and this  means also that the onboard battery is larger than those of a single phase system. What good about this system is it can be used on single phase full wave stator by just omitting the other two yellow wires.

By determining your system, you can increase the power available for your additional accessories that is needing huge amount of current such as high intensity discharge for your headlight by upgrading such system, increasing battery alone will not help.

Aftermarket China voltage regulator on the other hand uses different wiring configuration..

but still they are utilizes for a three phase  charging system., again they can be used on single phases with stator not grounded at the other end...
