HI y'all,
We used to use a buzz box third leg stimulator, when running 3 phase 
motors on a honda single phase gas generator. I got the thing from my 
regular electric wholesaler. I don't know how it would work on an 
inverter. The instructions in the buzz box included wiring for a three 
phase motor with no load to act as an autotransformer to balance the 
three legs. It worked ok.
