Hello all,first of all, my condolences to the family and friends of the founder. I am trying to locate the stator on my motor. I believe it is a 2008. Thanks in advance.

Thanks for the reply. Now I just need to know where the stator is. I'm looking on the left side at the long silver cover. Is it behind that? Everything I read tells me it's behind the cooling fan, but mine has an electric fan. And I don't want to just start taking parts off till I find it. I assume it's not on the right side, because the oil dipstick is there. Help......

Why do you think the stator is bad? Have you checked its output?

I was told by a scooter dealer that it is my charging system, I bought a voltage Regulator, rectifier and it still does the same thing. When it is started voltage is fine, after about 5 miles on the road it starts drawing off the battery. Then when you shut it off and try to restart it, the battery is dead

[Alleyoop]

Get a multi meter and test teh voltage at the battery terminals. Start it up and rev it up to around 4-5k and see what it registers. Revving it up around 4-5K it should register 13+volts or 14+ volts. If it does not register that high with high rpms then the first thing is to make sure your battery is good and it does not have a weak or bad cell. Take the battery to a auto parts store and have them test it under LOAD. If good then you can test the stator to see if it is putting out to enough to the R/R if good then you got a bad R/R/.

Ok, thanks, I've already replaced the R/R

[Alleyoop]

Good but it does not mean the R/R is good most all parts are made in china and no guarantees on them. Best you can do is test the STATORs output to the R/R you probably will find 3 yellow wires they should register 30VAC and when revved 50+VAC which would tell you the stator is good and the problem is a bad R/R or battery or both.

You might have a bad blocking diode, which controls the R/R to charge the battery. It is like a one way valve and is close to the R/R. I have had the same problem with my scoot. Finally found a diode that would replace the one on my scoot, does not look like the oem.

Here is the one that I used....

Ok, I started the scooter and the tail lights were very dim. I disconnected the stator connection and put a multimeter on the left yellow wire and the neg (from the multimeter) on the wire that is horizontal in the connector while it was running, I reved it up to 4-5 rpm's. The meter jumped to 96vdc.

There are THREE YELLOW WIRES you have to test all THREE not just one. The other two yellows should also register high.

Ok, so can you tell me how to check each of these wires? And what voltage I'm looking for? Thanks
