Ok Paul
I now start inverter WITHOUT IGBTs present and get this msg...

AC controller firmware, ver. 1.0
Desaturation Detection Fault! That's actually pretty bad.
Undervoltage Fault. Either your 5v or 24v supply dropped too low.
High pedal lockout fault. Ignore this for now. It's not really a fault. haha.
There was some hardware caused fault, not originating on the microcontroller (not set by me!
Throttle out of range! Is it unplugged?

Do you think desat is there just because IGBTs are not there or is it serious?
Undervoltage...huh i get good voltage on both lines. I did add small wires from pin 8 of driver chip to GND of the nearby cap like i saw you suggest in forum.
