Where did you pick stator up from

What do you mean, where I bought it?
It was the $31.50 from partsforchinesescooters
It was pretty beat up looking with one of the coil plastic guides chipped and in general just looked rough but it looked well made enough to work for the rest of the scooters life. Wish I would have gotten pics but I refrained because I was trying to focus.

Scoot started right up! she lives!
Took it around the block for a few minutes, ran perfect!
Going to splice the connector for the charge/lamp coils and test that later on today (probably at night so I can see at what RPMs the headlights fully light up)
Should work though!

COOL!Give us the run down,8 pole flywheel + 4 pole stator??

exactly, 8 pole flywheel and 4 pole stator.
Resistances were slightly higher on the 4 pole stator vs the 8 pole stator (it depends on how many coils, more poles doesn't neccessarily mean more power)
As far as I can tell, it's running the same, if not better than if I used a 4 pole stator with 4 pole flywheel!

The discussion on Stators has been a lot of fun to read  |

The discussion on Stators has been a lot of fun to read Considering the lack of info I found on the web for stators in the way we are using them, I'd say we've gone where no man has gone before. |

Here's some pictures of the stator wiring running up the shroud and stuff   |

So I put it on the stand at the edge of the garage, because it was raining.
No lights at all.
Battery voltage stayed at low 12v regardless of throttle.
check the connector for the two and I do have continuity, with the same resistance reading as before.
Any ideas whats happening?
Also, what voltage should I be seeing from the charge/lamp coils at idle/rpm so I can test output?
I'm seeing like 2.8v/1.9v on each of the wires, idk if thats enough though.
I'd think I would at least see SOMETHING

You should have AC voltage out of the stator(did you have your multimeter set right?).Voltage reg has a rectifier to change it to DC to charge the battery.Need to check AC at stator,then DC at battery..

That will suck if the battery charging doesn't work!!

I did set it to VAC and it gives me like 2 volts on one coil and 3 volts on the other when I was cranking it. Just took it for a ride during sunset and no lights at all, even going 50mph at near 9000 RPMs no lights. Really strange, any ideas? I figure if it cranks at 1000 RPM @ 3V shouldn't it be getting 12V @ 4000 RPM then? (volts generated is linearly based on rotation speed) Also, with the old stator it DID turn the lights on when I was cranking it, so I think the rectifier was working to begin with... I'm thinking this sounds right? scootdawg.proboards.com/post/297689/thread |

Looking at the TGB manual; www.49ccscoot.com/manuals/TGB_%202T_Service_Manual.pdfPage 15 and 16 wiring diagrams The red and white wire (#8) AC from stator goes to the autochoke,headlights,brakelites,and rectifier.. That'll be your AC power supply stator coil(s) to run all the lights..Put your multimeter on AC 200volts and attach to unpluged red/white wire at the stator,crank it up and check the AC voltage at different RPM's and report back.. Double check all your grounds too! |

Double check all your grounds too! Yeah it gives like 2-3v at idle and 5.5v is the highest I saw at like 6k RPM (couldn't get it any higher on the stand without it wanting to take off) So looks like its just the 4 pole stator not working right with the 8 pole flywheel. Strange that I get the correct volts from the exciter coil though... Got two options now: 1) Rewind and repair current stator 2) Buy brand new stator from mfr. direct I'm going to get some quotes for option 1) first and then resort to 2). |
