R/R = regulator/rectifier, it regulates the voltage levels so you don't blow bulbs or overcharge the battery, and rectifies the current to DC.

Both the white and yellow wires read at about 10v ac when at low rpm (1800). It then raises to about 12v when twisting the throttle.
What should I be looking for for the cause of this issue? The stator is relatively new, I got it around 3 months ago.
My old one was fine however I had to make my own pickup coil out of the old pickup coil from the CVT that would be used to pickup the clutch revs if I had a limited CDI, and in doing so I mutilated the wire TO the pickup coil.

Hmm... I think I'm going to try to use my old stator coil with my newer pickup coil, see if I get some better voltage and check out the newer one in the process.
I think it's weird tho I don't have issues when the engine is cold with my issue starting, the issue always comes up after riding for a lil bit. Though the starting issue does not seem too severe, I am still able to pull the throttle when I feel it trying to start but have issues and it usually starts.
Can stators possibly create static or something or maybe a loose wire would cause this issue where it's not outputting what it should? I'm no pro at generators, I just know how to hook up things and solder.

10v looks low to me, defective stator perhaps?

I installed my old stator and used the newer pickup coil as to not worry about the old pickup coil. The power to the lights is still 10v at lower RPMs. It is daytime now though so I cannot tell if the lights are still dim or not. I suppose I will find out tonight.
Could anything after the stator effect how the stator works?

10v AC does seem to be very low. I just finished upgrading my 8-pole stator to 11, so I have some recent measurements before the upgrade.
With my 8-pole on a 150cc I was getting 18v AC from the yellow wire and 20v AC from the white wire.
At the R/R plug I measured 16.5-17 on the yellow, and 20-21 on the wire.

I went for a ride earlier to get home, it was already night time. I noticed the headlight is SLIGHTLY better now while moving, but still very dim when idling and does not start to get brighter until about 2500rpm. It is the same as when I had the other newer stator in there, but the newer one was not making the lights brighter by much while moving.
I noticed what sounded like small electrical sparking under the tachometer I installed or maybe behind the light bulb while at about 6000rpm or so (it's hard to check and avoid boston drivers). I was sure I isolated the positive lines and the pickup, but maybe I did not secure them enough for the vibration. I am going to check tomorrow. Last time I heard the sparking noise it turned out to be one of the metal bulb terminals had come out of the plastic bulb holder and was crossing with the other wires. I really should get a new bulb holder with wires that aren't falling out... I burned so many bulbs until I figured that out, however I never had any stator type issues or dim lights when that was happening so I think it is unrelated.
I also noticed that when I tilt the scooter sometimes it acts like it is bogging, but seems like an electrical thing. I am also going to look at my negative wires to check for bad grounds, or maybe I'll just throw a bunch of wires onto everything and to the frame and connect it all to the battery like I did last time I thought I had a bad ground, lol. Grounding web!

I forgot that you installed the new tach. Did you put it on the AC circuit or DC circuit?
On my TaoTao only the headlight, brights, and enricher run on AC. The rear lights and turn signals run on DC.

I hooked it up to the DC I believe, the tach turns on when I turn the switch. I tapped it into the black wire on the ignition. |

I took the body off my scoot and inspected all the wires. I found a green ground wire coming from the front of the scooter going back to the frame where the engine ground connects. It was loose and looks like it is all burned up. The end of the wiring was all black, I cut it an inch down, still all black, cut it another inch down, still all black but with shiny copper cores but still burned on the outside of the copper but not the outside of the insulator. I ended up cutting it too short so I connected it directly to the negative on the battery.
I then for safe measure made a couple grounding wires, 1 foot 12 gauge each. One going from the frame to the negative on the battery and one going from the same part of the frame to the valve cover.
I noticed on the negative terminals for the tach there were burn marks, so I believe it was sparking from here when I was riding. I wrapped them up with a bunch of electrical tape, wrapped the positive wires too even though they were still wrapped good, you can never be too safe.
I started it up and immediately could tell it was running much better, and started easier. The engine sounds so smooth and idled up to 2500 before I turned it down. It was last idling at 2100 yesterday with the same settings as when it idled at 2500 today after installing some extra grounding wires. I will see how the lights look tonight.
I now believe I need all new wires. I need a regular loom for my scoot, no extra connections needed as I have my accessories on other wires.

That's good to hear. Is the headlight still dimmed?

That's good to hear. Is the headlight still dimmed? Yup, but everything else is working much better. |

My bulb got disconnected because of vibration and the holder and the bulb fell out, but then all the other lights and the dash was bright. I am guessing my problem lies between the light bulb and wherever the bulb draws power from (the rectifier?)
I hate this weather, if it weren't for the snow/rain/sleet/hail going on right now I'd be outside tracing the power line for the bulb to see where it connects to.
