Could someone please give me the correct stator output for a 150cc 4t scooter. I cannot seem to find it.
Thanks, Bill

How many coils are in your stator , what color wires ?

John,
I replaced the stator with a new one I have really dim headlights almost not on. I replaced the stator due to the scooter stopping on me and having no fire. Know I have fire but no lights. All grounds are tight did not change anything when I put the new stator in. Could the flywheel be bad?

I think I did not write that correctly it has a yellow, white and a green wire in the plug.

Here is the thing the Stator FEEDS VAC voltage to the regulator which in turns converts it to DC to run the lights and Charge the battery. So What I would test right now is to see if the Regulator is putting out enough to charge the battery and light up your lights. Get a Volt meter and hook it up to the battery and see what it reads. Sitting there it should read 12.5-12.volts. Start the motor and rev it up to around 3-4k rpms and see what the VOLT METER reads. It should read 13+ volts if NOT get a new Regulator/Rectifier.
Now it could still be a Bad Stator even though it is new, but I would not think so.

I found how-to test from ScooterDoc forum Alleyoop To test the output of the stator set your multi to AC and find a good ground for the black probe such as the engine or frame. Unhook the white wire from the regulator and put the red probe into the connector on the white wire. Start your engine and give it some RPMs. You should get something like this:  Reconnect the white and unhook the yellow. Test it in the same fashion:  The white provides the charging current and the yellow does the AC lights like the headlights. If your voltages are somewhat different don't panic, there's a lot a variation from one stator to another. However, they should be close. If your voltages are significantly less on either wire then your stator is toast. If your stator voltages are OK then hook all the wires back up to the R/R and start the bike. Now touch your red probe to any exposed spot on the yellow wire. It doesn't matter where, the whole wire is regulated. You should get close to 12v AC. Then do the same to the white wire and you should get 12v AC again. If you don't then the R/R is bad.   |

looks like Alley had the charts , I will only disagree with one statement "when the white wire is connected to the regulator (being it is for charging the battery) its voltage is not significant ". The reason I say this is because the regulator is converting this line from ac to dc then dumping the excess , so with that said you could have a low voltage reading or a high voltage depending .
Via the regulator the yellow wire will be regulated by the regulator . The regulator will load the yellow wire to keep it at 12ish vac . When you load a wire down you bring it voltage down , example of load your headlights . If the stator is generating the full 20vac no load , then with 50 watts of lights/load it may become loaded down to 15vac . That is a bit on the high side so the regulator will load down the wire to 12ish vac .
Digest above .
If you do the voltage tests via Alleys chart and the white wire is 12ish volts and the charging voltage is low , it might be that the regulator has been changed . There are 4pin regulators with different pin outs , I have heard of switching the yellow and white wire positions on the regulator solves this problem .

John,
Well I have checked it out and evidently I have another bad stator. I have no idea what the heck is wrong with this scooter.
They sent me a new stator and it is the same as the other one. Now I know what you all are going to say so I will cut you off ahead of time. lol
Yes it is installed correctly. I just can't figure out why it is not putting out enough current for the lights. Now, if I try to run it like this it starts to run for a mile then stops, then starts up and runs but real short then stops and it will continue to do this I am not sure if it is not putting out enough current to fire the coil and CDI or what.
I have never had a scooter that I was ready to give up but this one has me ready to give up.If anyone has any ideas on this thing other then it is CHINESE lol I want to hear. Again I want to thank everyone for all your help.
Bill

What are the voltage readings ? do it with the regulator unplugged .

check to see if you have a grounded or ungrounded stator, they require different r/r's. unplug your new one and read resistance to ground through the white and yellow wire. a couple ohms is grounded, no reading/OL is ungrounded, then test the original and see if they are the same.

I will have to check that on Tues because my scooter is at the shop not at my house. I just got the same 6 pole stator that was PFS had. There are no wires that go to ground on the stator. unless it is the green wire goes to a ground trough the wiring harness.
