UPDATE:
After talking to Tom at Flight Systems. He gave me the resistance readings and pinouts to check brushes/stator/quad readings. All checked OK. After another phone conversation with him, He wanted me to check the freq output of my generator. I was only getting 55 hz. He said that their modules will decrease the output voltage to 90VAC if the freq drops below 57 hz. I adjusted mine up to a no-load setting of 62 hz. Looks like the governor spring is weak (probably due to heat).
I hope all this info may help someone else.
