I've been studying the wiring diagram to understand how the stator is connected. The diagram is a typical simplified representation, so it's not helping much. These bikes were described somewhere as having a full DC electrical system, but that's not the case.
Look at the stator symbol and you can clearly see a yellow wire shown tapping off partway up the windings. That yellow wire goes to the regulator and headlight. Thus the headlight runs on AC current.
The black wire shown at the top of the windings goes to the rectifier and comes out as DC current (red wire).
I haven't pulled the stator off my bike to investigate, but there is a stator picture in the 2011 manual (though not neccessarily a 2011 picture).
There are 8 posts on the stator. The one at 225* is obviously the ignition winding. The smaller one at 180* has me baffled. What is it's function? I can't make out the others well enough to see if they are all identically wound. I'd like to know how the various windings are connected and where the ground point is.
I suspect that 3 of the larger windings are used for AC only, and 3 are used for AC rectified to DC. I intend to mount some LED offroad lights instead of the stock light. LEDs will work on AC but won't be as bright. The issue for me is that I want to use a PWM based dimmer that needs DC power. Using the dimmer to drive an AC switching device is clumsy, so I'm considering a second rectifier for the headlight circuit.
If the windings were all in series with the ground point at the bottom end, I would ignore the yellow wire. Does anyone know the actual rating for the stator? I guess it will be something like 70W at 7000 RPM.
