you could parallel the windings and put full amps at 120 on the twist lock and use a twist lock to RV adapter, use only (1) of the 23 amp breakers , but you might trip out the breaker when it comes time to run the A/C and the MW at the same time

the current configuration is 1 winding per duplex and 230v at 23amps at the twist lock, no way to go to 120 only with out moving wires, whether its cutting, or unscrewing, things have to be moved

It is not phase reversal you are trying to do. It is parralleling the 2 winding in phase. Out of phase is what you got when the ginny loaded down and put out no voltage. As to why only 4 volts when in phase that is a tough one.

This thread has been very entertaining and informative. Maybe I can offer some insight to the low output issue with this generator.

The problem with parralleling the coils in this generator (assuming that the schematic is correct) appears to be caused by the way the AVR input voltage is derived from the main windings. The AVR voltage is obtained from a portion of *both* main windings, not just a portion of one winding as in many generators in this class. When the windings are converted from 240 volts center-tapped to parallel 120 volts, the configuration of the AVR tap points change and the voltage applied to the AVR input is probably increased (it depends on the location of the tap point), the AVR lowers the field current to bring the AVR input voltage back to what is expected and this results in the low main winding output voltage. It would be helpful to know what the normal AVR input voltage is under the original factory configuration. Depending on the normal AVR input voltage and the adjustment range of the AVR (if it is adjustable) it might be possible to reconfigure the tap points.

However, it is entirely possible that this generator may not be able to be configured for full power at 120 volts without rewinding or at least moving the tap points in the main winding.
