Well,,, i think we are getting somewhere, after brushing a few grounds to the metal,,, IT SEEMS TO START CHARGING !!! the R\R becomes warm and the voltage holds...
I might have a weak battery,,,

Hi, money is no problem... charging the battery IS the problem...
I took these readings:)
Engine warm, idle, R\R not plugged, Yellow = 22 VAC White = 25 VAC
Engine warm, half throttle, R\R not plugged, Yellow = 38 VAC White = 40 VAC
Ground between and frame was not too good, bolt not very tight and a lot of paint... all fix now..
Will take readings every thing connected...

Hi it's me again:)
1.) It is not the passing switch which is VDC
2.) The only thing I found is, I think, the automatic choke which is fed by a yellow wire, the other side by a green wire...
3.) the tail light and the brake light are VDC fed and they are ok.
4.) The reading between the yellow to ground is 0 omh since it goes only thru a coil...
I'm now going to work on the bike... more to follow...

Can you tell me where is the famous ''hi-low beam relay''?

Good day JR, I'll like your answer,,, something is wrong so lets find it.  1.) I work with the electrical schematic your referred to. 2.) Last evening I rev the engine with the R|R disconnected and the Hi beam blew, therefore telling me that I got too much VAC when not furnishing 12 vdc, but I'll take the exact reading this evening. 3.) The magneto seems well grounded and I join the green wire from the magneto to the battery ground directly on the scooter frame.. in any case, I'll clean all my frame ground to the metal this evening. 4.) It does look like a ground problem... but everything looks ok... now that I know what the voltage should be when reving the engine I can continue fault finding. 5.) More info... the R|R i installed is a perfect full wave (diode)bridge rectifier (http://  .electronics-tutorials.ws/diode/diode_6.html) which I verify with the ''diode'' setting and it looks perfect (it's new) the old one seems to have only one diode left... 6.) The only parts I didn't find is the famous ''hi-low beam relay'' and it could have an impact on the VAC... 7.) For your info... when every thing is connected, the more I rev the engine, the more I drain the battery...  Thanks for your help... it's very appreciated. Mike |

I agree,,, but you never know when everything is going to blow  |

and which one would be the ''right'' R\R? I ordered this one thinking it was??? it"s the part number they give on the schematic...

2008... I think I'll bypass the voltage regulator... Install a bigger battery (ATV) type and buy a good battery charger... Start with the footcrank.... what do you think of this plan...  )) |

shit,,, not looking too good ,,, I already change the stator (8 poles) and the regulator... What I got in hand now is a basic full wave rectifier (4 diodes, 2x2 in séries...) anything to do with that? |

Yes I have a good meter for that. yes the old regulator looked like this one AND it was shorted to the body of the R\R... but the guy before me change the R\R 3 times... so...what was the original? But I can see that the pinout is not the same one between the old one and the on I got (reply # 2)

Headlight is AC, the battery is totally remove from the circuit at this time. When I plug the red wire I can read around 5 or 6 vdc but when I plug the ground it goes down to 3 VDC,,,

yes, I cleaned the frame to metal first and bolted it solid, but no pin is short to the body of the R\R?

Hi, Ok, I plug the wires as the picture, everything is fine until I plug the green (ground) then my VAC which were 27 vac on yellow and 22 vac on white, dropped around 3.5 vac??? NO pin of the R\R goes to ground??? So near yet so far ) Please help !!! Thanks |
