I think it only has one capacitor, so it must stay in circuit all the time. Sounds like a good plan to put the starter only in with the run winding. Bryan have you tried using one of those starters you have? That looks like it is for an air conditioner. I can't quite figure out what they are doing with that starter, but it looks like they are switching the start winding out of circuit after it starts. Doesn't quite make sense to call the capacitor the run capacitor in that case. Most motors with only one capacitor and no starting switch just leave the cap and start winding in circuit all the time. Thanks for the input Mike. I have ordered a two wire soft starter, and will give it a try wired into the run winding only. I did think that I may be able to use a drill and run the motor up to speed a bit then hit the start button. I may try that tomorrow. Once it gets going the inverter should have no problems, I hope. Thanks Pete
