Lifan 140cc (1P55FMJ) prepping to add headlights

[BlackHornet]

Hey guys, been a lurker for a bit now but just joined because I am needing some assistance and I havent been able to find the information by browsing. I am hoping somebody here could shed some light on my issue(s):

I am wanting to add some LED headlights to my pitbike that has a Lifan 140cc motor in it. I pulled the flywheel to check out the stator that it has and it is a 6 pole stator with Black/red, white, green, Blue/white, and yellow wires. The white and Yellow wires are not connected to anything because the bike never had any lights, so I ordered a 4 pin rectifier and hooked it up according to:
TBolt USA Tech Database - TBolt USA, LLC
the top picture.

Green (Ground) hooked to bottom right pin
yellow is upper right pin
white is lower left pin
Red from the top left pin

I took my multimeter (set on DC) and checked the voltage from the red wire and a chassis ground and got between 8v (idle) and 14.5v (revved)....then I hooked an 18w LED bar to it and at idle it was flickering (LEDs flicker on low voltage) and then when I gave it throttle, it blew the light.

So I started testing other wires with my multimeter set on DC and AC to see what I could possibly find out. I got voltage readings from red to ground, yellow to ground, and white to ground regardless if my digital multimeter was set on AC or DC. I swapped the yellow and white wires on my rectifier and got the same results, just a little lower.

Looking at T-bolts page that I linked, should I try the diagram on the very bottom? Would that mean to make a jumper from the top right pin to the bottom left pin and then leave the white wire coming from the stator not connected?

Is my rectifier messed up?
Is my multimeter messed up, since I was getting readings when set on DC and AC from the same connections?

Any help would be appreciated it.
