Tried googling this most of the afternoon without much luck. Basically if I have enough AC voltage at the CDI, and the battery is still not charging, must be the regulator/rectifier?
Measuring the battery voltage while the scoot is running and it is not going up as I rev it.
Need to measure the voltage off the stator first, but wanted to see if my logic of thinking was correct?

Yes and no. If it runs voltage to the CDI has nothing to do with charging so that's not an issue. Now first thing is have you checked to see if you have a fully charged battery? By fully charged I mean if you slow charge it for 3 to 5 hours, let it sit for one hour after charging it reads a minimum of 12.5Vdc or better? If this is the case then at idle it should read 13.0Vdc+ and go up to around 14.0Vdc at 5k RPM. If not then yes you need to check the stator and here's what you'll be looking for:  |

Battery is a brand new 12v, 9AH battery. One thing that I noticed is that there is only 3 wires that appear to come from the the engine. One's blue/white, one white and the other yellow I believe.

Means nothing, did you test the voltage with a meter, if battery is low so will the charging. Should have four wires Bl/W, white, yellow and black/red. Green is ground and could be coming from the frame to the R/R where the black negative battery cable hooks up. No ground from stator means floating ground. Need to check battery charge with your meter. JR |

Here is what I took for pictures. I'm not sure where these lead to. The scoot starts and runs. Just isn't charging the battery from what I can see. Yellow, blue/white and white are the colors Attachments:

Also how do post pics with photobucket, still haven't figured it out Attachments:

you click on share a page comes up then click on links and go down to the 2nd from the bottom it says IMG click on that and it copies then paste it here.

Take a picture of your Reulator/Rectifier so we can see the wires in and out.

Yellow, blue/white and white are the colors Yellow white = stator wires going to regulator/rectifier (R/R) what I think you have confused with CDI. There will be other wires going to CDI. Did you unplug it from something that looked similar to this?  Now you need to test the AC voltage on the yellow and white wire to ground with a meter. You can do this with just the engine turning over, not running. Also what make, model and size is this scooter? JR |

Scooter is a Roketa 50cc 4 stroke. This is the R/R out of the scooter. I can take another picture but this is the only one I had on my comp.  Hard to explain without lots of pictures, but that 3 wire plug that has the yellow, blue/white and white comes directly from the engine (pictured above) and goes into the upper right spar of the frame where all the other wires are mounted on this scoot. Thanks alleyoop. I think it wasn't showing because it was set to private. |

On the right track, your other pictures didn't show up. I know what the other wires are to and was this plug plugged into a female one?
Yellow and white go to the R/R and blue/white goes to CDI.

Thanks JR. Little confused on what to do next? Some reason still can't get the img photos from photobucket to work. Public profile is on and what not. I'll just attach pics through attachments I guess Attachments:

JR, yes that it was plugged into the female end in the harness. These two pics are the wires from the engine to the plug Attachments:

Plug it back up and it's common for wire colors to change from one end of the plug to the other, Chinese way of doing things. Ok you did for sure find the R/R up at the front of the scooter and this means you have the headlight/s unplugged which is good. We don't want to blow the bulbs.
Get your meter out, set it to AC volts 100ac on the scale,
Unplug the R/R
Start the scooter
Test the voltage on the white wire to ground, write done the reading
Test the yellow wire to ground, write down the reading.
Do this at idle and about 3k RPM's and this will tell us if the stator is putting out like it should. If it is and you find no bad wires or connections going to the R/R then it's time to replace it.
