Bad Stator or Reg/Rec?

Still struggling with powering my ‘75. Bike is running and riding great. Kicks over on the first try without fail.

I wired in my HHB PMA kit with supplied regulator rectifier but have no power coming through for lights. I have 0.6 ohms resistance between my two yellow wires from the stator (recommended 0.3-1.0 ohms) but no power measured while running either from stator wires or on the down stream from the reg/rec.

Any suggestions? I am at my wits end here. Reg/rec is grounded to the frame as updated from my last post.

Thanks to anyone with insight.

I would recheck wiring
If I see right there is an open end blue there 1 o clock
That maybe should be connected if not capped

7 o clock there is a ring and red Wires .the connection is not up to spec
If no connector in house maybe solder and shrink wrap

Be careful electronic regulators can fry instantly without smoke or sound if connected wrong

Both those can short to ground if unlucky If I se right
At least some electrical tape temporarily

Those open connections are for the headlights unfortunately. Not related to the reg/rec and fuse box yet unfortunately
 
It is dangerous to run circuits without ,,load at times
No Experience with PMA
But is it not magnets running close to a coil and should create Voltage.
If I get it right you are measuring Resistance on the Only 2 wires coming from stator
and it has correct resistance Please correct if wrong

I dont know how the regulator looks But those 2 should enter the regulator at the right pins
And there is More wires ? 1 or more
Please give info
One can be ground if so I would consider pull a separate wire all the way to battery minus.
To ensure ground

Please give more info on circuit and regulator

Why not hook up the lights ?
but have no power coming through for lights.

Update; the stator for HHB was wired wrong. I sent it into him and he rewired it. Got it back, hooked it up and boom, power! All good now. Running and riding
Hi again MedicWild, just saw this thread, so you can disregard my comment on the other thread. I'm glad you figured out your issue, it must feel glorious. I'm still working through mine, but this is all good info. How did you come to the realization that your stator was wired wrong?

No worries man. I came to the conclusion because I rewired my entire bike three times and while I could get it to run, the lights never once worked. So it was mainly out of frustration and stubbornness I contacted Hugh haha. He was great though

I might have to give him a shout soon myself, although with the state of Asheville I'm sure he's busy. My stator was purchased in December 2023, I wonder if it's from the same bad batch...

Very well could be. I bought mine around feb 2024 from TC Bros so maybe they had the batch sitting on their shelves for a bit. Hugh was pretty receptive about it. I sent photos of how my bike was wired how I originally planned it, then I took the reg/rec off and mounted it directly to the motor as a test (didn’t work obviously), then sent it in with a note. He gets a lot of folks whom don’t ground correctly I guess. Because of his willingness to help I have no reservations about ordering more kits from him.
