i got a bike with just engine and frame and really old wiring harness so im a little confused on diagrams as i dont have a main switch and they dont show a white wire.
help me understand the 2 lighting coils?  there are 4 wires coming from stator.  all i think i know is the black goes to ignition coil. 
i think the yellow goes to headlight and the white and green are battery if im correct?  or whats what?  i got a rectifer and a 6v battery.  i got some regulator but it only has one yellow wire coming from it so im confused. i got it off ebay as i think it said 6v regulator.  what fuse to use?  is it possible to do some wiring diagram without main switch?  whats confusing is some later 70 model seem to only have 1 lighting coil if im right.  i cant tell much from old harness except voltage regulator is like a magnet coil thing.  plus i got it in parts and didnt take it apart myself so any help is much appreciated. thanks
