So I've searched the forum but can't find my issue. My headlights are solid and bright at idle, but when I get the bike they flicker and dim a bit. Still on, but dim sum. I have an aftermarket rear led tail light and integrated turn signal. Though I have no idea if the flicker is related to that or not, as I donít know when the issue started. I have a year old Yuasa battery in the bike and new spark plugs if that matters. I don't own a multi multi-meter so have not been able to check voltage at the battery. Oh and the bike runs fine.
All right so this is what I’ve learned. The wires from the alternator test properly for resistance and they don’t ground out to the bike at all. I have not yet checked output from the alternator. What I have learned about the RECTIFIER is not good. I'm not much good with a multi-meter but I hope this will make some sense. With the multimeter set to continuity/diode I get the first vale. (Sperry DM-6400 multimeter) with it set to 20M for the Ω reading I get.
Negative on BR, positive on B1-3 then BW 0.549,4.33\0.555, 4.38\0.558, 4.43\0.961, 6.24
Positive on BW Neg on BR B1-3, 0.961, 6.24\ 0.521, 3.78\ 0.518, 3.72\ 0.515, 3.72\ NA
Any other combination and I get nothing.

Found it thanks. still not sure if my numbers are good or bad as I dont have any reading for most of the grid. What I do know is under the no load test the bike is putting out between 65-70V on each of the black wires. So the Stator tests fine. Just need to find out if the rectifier is good. I know that all wired up the bike is about 13.5v at idle and 12.8 at 5Krpm so somthing is wrong.
