Question G2-A charging system

My 1990 Yamaha G2-A stopped charging. I replaced the VR (voltage regulator), the SG (starter generator), then the VR again. I've checked continuity on all of the wiring and ohmed out the SG at 5.5. Bypass test shows that the SG is working, but when I plug everything up, no charging. Is there a switch that changes the starter into a generator after the engine starts? Any help or advice would be greatly appreciated!
