Bashan tvnacman Guitarman Alleyoop I checked the voltages again on the stator. The W or Y wires were reading well over 40V AC at high revs: 60V to be exact on both wires. Bad stator? Could not find charging diode.

I was busy last night and not able to work on the bike. It is a 2008 Qipai QT150T-6. I bought it from a guy that said it was almost brand new with only 500 miles on it. I am coming to the conclusion that the new, good parts were taken off and replaced with old, worn out parts. I will work on it tonight and let you guys know what I find. Maybe it has a charging diode!
Thanks again for your quick responses, knowledge, and humor.

Bashan tvnacman GuitarmanThank you for the quick responses. Bashan, I checked the Y and W from the stator with the stator unplugged. The AC voltages on both wires were in the 8 to 9V range at idle. With the engine rev'ed (I don't have a tach so I don't know the precise RPM) the voltage on either the Y or W were 32-34V. I don't know the age of the battery. tvnacman, What gauge do you recommend, 12, 10, 8? Most of the wires look to be 14-16 gauge. Guitarman, Where on the scooter would the charging diode be located, most likely, and what does it look like? How would I test it?

Bashan, JR, Alleyoop, I have read some other threads related to charging system problems. They have been helpful in getting my bearings on where to start troubleshooting. So, with that being said, however, I still have a problem with the charging system. I checked the voltages on the stator. Both the yellow and white wires read between 8 to 40V AC. I have replaced the Rectifier/Regulator but the battery is still not charging. With the motor rev'ed, voltage at the red wire on the R/R is only 12.85V DC, and same at the battery. I have checked continuity and there are no broken wires or loose connections. Where do I go from here?
