Anyone repair inverters?

well, I pulled every MOSFET and diode pack in the edges and found another MOSFET had gone bad so I ordered 10 new ones ($2.40!) and will try one more time. I did locate the PWM driver chip and if the 8 new MOSFETS dont get it working, and possible a new PWM chip... its gonna get donated to anyone that wants to cover shipping. As far as I could test, the windings are not shorted between the poles.
