Hello, I have gotten some great info here in the past and have run into a problem i could use some help with.

I am swapping a 50cc kazuma engine into a ct90 frame, the engine has 4 forward gears and is electric start only, it has 5 wires coming out of the crank case.

Now that i have it running I don't think the battery is charging. When I rev up the motor it shows about 12.8 volts with the battery in place, without the battery it reads 5- 7.5 volts. The yellow wire going into the regulator reads about 10 volts ac. I thought it might have a 6 volt regulator so I swapped it but the voltage remains the same.

Is the stator going bad, or a wiring problem? any help is appreciated, Thanks!
