Should anyone be confused, i don´t know if this diagram (big word for something as simple as this Paint-drawing) makes sence?

...and just to state the obvious:
It doesn´t matter if the grey wires is mounted or crossed one way or the other on this set up, as long as both of them end up on a free AC leg on both generator and diode bridge.
One could could just as well drop the grey, red and black wires on the drawing entirely, solder the AC legs directly to the generator, and mount the DC legs directly to the "accessory".
I just chose to wire mine up as i did, since i don´t like the look of the parts hanging out there in the open.
