GY6 Charging issue

[flexo6]

I put new stator in and checked voltage at regulator ....while voltage regulator was plugged in and scooter running....black lead to green ground and red lead to yellow=10.5-11 ac volts.....to low.
Black lead to green ground and red lead to white=18 ac volts...good!
Black lead to green ground and red lead to red wire=12 dc volts....to low!
When I unplug regulator and check voltage coming up from stator...voltages are good to yellow and white wire.
I tried 2 different voltage regulators with same result.......I ordered a new regulator just to make sure the 2 I have aren't bad....anyone have any other ideas?....TY!
