I ordered a stator for my 2011 Peace Sports 50. The bike has an 8 pole 5 wire stator. The one I received has two poles wrapped in black. Otherwise it looks about the same minus the plug being one unit on mine but I can replace the plug with the original. Why does it have 2 poles wrapped and will it be okay to use? I have spent 2 days looking for answers.
Thank you.

Follow the wires. The wires should connect to an end of a winding, or to both ends of a winding. Compare the wire colors to the original. Compare what is connected to what wire original<>new. See what is left un-matched.
You could have a winding that has a provision for an accessory output, such as to power a USB charging port. I have one so equipped, but have not looked to see where it gets its juice. Could be for aux lighting, such as another always-on-when-running light.

Maybe you or someone will help me make sure it's okay to use. |

Looks pretty much the same. Just match up the wires.

- For the most part, the wrapped coils are just 'clocked' to a different spot. Rotate one or the other of the two stators until the wrapped coils align. One has black wrapping, the other has white wrap. Rotate the black wrap until there is a black wrap at about 2:00 o'clock. Move the white wrap just a little, and the two look like each other except for the color.
Look at the wires leading away from the stator. The W and Y are generally for the charge system. The others, you can figure out using your wiring diagram, or follow to see where they connect. One will generate power to run the CDI on most.
The POSITION of the coils does not matter, EXCEPT the one for the CDI. AFAIK, the others can be anywhere in the 360 degree rotation without affecting anything as electricity is not 'timed', spark firing is. AFAIK.

AFAIK. tom AFAIK The only CDI coil that position matters is external to the flywheel and controls ignition spark pulse timing. |

Frank, is there not a winding that produces the AC current used to operate the CDI? I don't know where else it could get ac to operate the CDI. The 'trigger' is the blip of metal on the outer diameter of the flywheel passing by the pickup coil, generating the tickle that tells the CDI to fire... but maybe the AC doesn't have to be exact, as it could be charging a capacitor. Yeah, details. Guess it does not need exact timing, but it has to generate the AC before the trigger bobs past. I think.

The wrapped coils go to the CDI for spark. It's not like a computer that's running, or anything. It just stores the voltage from the stator, and spits it out when triggered.
The location doesn't matter, either. I changed from an 8 to an 11 coil, and they're in different spots.
To the OP, those coils are wrapped because the wire is much much thinner on those coils, to generate more voltage, as opposed to more amperage.

The wrapped coils on the stator produce AC power to charge the CDI power system for AC CDI units. The spark timing pulse is produced by the coil on the outside of the flywheel. The wrapped coils do indeed have thinner wires that are easily damaged and the wrap color is not significant AFAIK, just whatever the manufacturer has on hand. Some stators have two CDI power coils, some have one. Manufacturers vary.

Benelli andretti X50 minarelli QJ1E40QMB had a 8 pole stator as in pic I'm guessing it's DC cuz had no wrap on any the cdi and rectifier r DC question I can't find another stator that was in ther only a 6 pole with one for the pickup or pulse I'm guessing the 6 pole is a A.C stator I thot all stators pushed out A.C and the cdi and rectifier reduce to 12volts question I have if this is AC do I use a A.C cdi or do I use a D.C cdi bfor I messed with anything I noticed only taillight brake blinkers worked with key on headlights did not this scooter did not run when I got it ther was no spark. Any help would help thanks Scott

Headlights are powered by unregulated(partial?) current from one side of the stator output. Yellow and white are the two conductors generally used to feed the regulator/rectifier. The headlight only work with the engine running. They do NOT use battery power. The tail light, blinkers, cluster lighting, and fuel gauge are powered by the battery when the engine is not running. In vague terms, you have two sources from the stator with the engine running.
A DC CDI needs battery power to operate. It should not need anything from the stator. It has a pickup external to the flywheel, mounted about 11:00 o'clock on the surrounding case, that senses the little square button on the flywheel as it passes, triggering the CDI to fire at some degrees BTDC. AC CDI styles have another winding on the stator, with a wire that provides AC output fed to the CDI for it to use as power source.
Not confusing if you look at the proper schematic or wiring diagram. Someone may note the difference between a diagram and a schematic...
