When the wires are unplugged from the R\R I got those voltages.... Yellow = 20 VAC White = 25 VAC Like I said, I think that we got the problem fix and that with a good battery everything will be fine Although it will never be a big charger  |

For sure with a good battery it won't take long to see and when you get the bulbs replaced you can get a better idea too. I am concerned about the AC voltage, my 8 pole stator does that output at idle.
We'll be here to help any time so keep us informed.

JR, Thanks for your help I really think that a good battery will give good readings. The scooter ran idle for 30 minutes and the DC voltage never went down. The R|R is hot and charging. With R|R unplugged: At Idle: Yellow = 20 VAC White = 25 VAC High throttle Yellow = 40 VAC White = 45 VAC |

...and you were right, the problem was the ground,,,
As I'm sure you know, this scooter's frame is in 3 parts,,, those 3 parts didn't make contact between them because of the paint.
Where the frame part's join, although the top layer where goes the nut was on the metal, the 2 frame parts where isolated by the paint (like rubber paint).
I started to get normal readings only after I put all these parts on the metal.
Thanks again, I'll do a refresh once I change the battery and the headlights bulb.

Awesome! I like those AC readings a lot better.

Hi guys... the results:
New magnetor
New battery
New hi-low beam
It charges but not fully, like if it would not be enough to supply all the lights AND charges.
The light is good in front. just slightly increasing with throttle.
Question: If the flywheel were a 6 poles and the magneto an 8 poles, would it work? (but not strong?
Anyways it is way better, at least even if it drains the battery, it does it very slowly now...
Open to all ideas..

Unplug the headlight switch when you start it for 2 or 3. Min then plug it back it and go. When your done with the ride unplug again for 2 or 3 min . It will charge up fine. Or switch over to leds.

 and what would be the logic behind this procedure? |

Your charging voltage will increase and top off the battery.

Anyways it is way better, at least even if it drains the battery, it does it very slowly now... Open to all ideas.. Good question? You used the flywheel form the 6 pole stator and just replaced the stator to 8 coils type? Eight pole stators put out more battery charging current than six pole stators. If given the choice go for eight pole. The problem with six pole stators is that you really don't have enough power to run a pair of headights and keep the battery charged at the same time. But remember that the stator and flywheel must match. A six pole flywheel has six magnets embedded in it. An eight pole stator has eight magnets in it. The magnets in the flywheel must line up simulateously with the stator poles as it spins. If you put a six pole stator in an eight magnet flywheel your battery charging system will not work at all. I have the typical 8 pole stator in my Bali and with a good battery I have never had it go down and I don't own a battery tender, never needed one. With both headlights on hi beam and my electric oil pump on at 4k RPM it puts out 14.1 VDC. Also change every bulb in the scooter except the headlights and it'll gain you 0.75VDc charging power and that's huge on a scooter. Change the flywheel to match the stator. JR |

measure the outer diameter of the stator , I have many 8 magnet flywheels . the ones I have are 89 or 90mm . Unpluging the head light switch takes off the load of the heaedlights=more power for charging . If the charging system is right on the edge of charge and discharge this will put you on the charging side , this works to replenish power used for the electric starter . I live in NYC I sit in traffic so I'm at idle often . When I was using the 6pole stator I needed the little extra to replenish .

If he has the 8 pole set up done right he can idle all day long with the lights on and it'll not be a issue.

The scooter is on the try and test now... Even if I started 10 or 15 times a day with little driving, it keeps going. All the lights are the way they should be on a new bike. So, it charges around 12.25 VDC and 12.5 VDC but doesn't seem to go down below that... I'll keep you posted as the test continues... By the way, I think the flywheel is an 8 poles like the stator, I just wanted to know if it would work (but weak) on a 6 poles... Does anyone owns a Baja SC50S that charges just fine, with all the lights on? Thanks again for your help and comments... GREAT SITE you got there |

By the way, I got a good 8 poles stator for sale  |
