Sorry - I didn't see this as a new post for some reason

Agreed - voltages should swing from slightly negative (-3V or -5V) to about 15V.

I don't have access to my controller - it will be Jan 2 before I can go home and look. I should look at that in any case to determine if I killed my control board when I killed my IGBTs, or if I just killed the IGBTs.

The IGBTs are driven (or they were in my version ) by through-hole connections direct to the IGBT pins. I don't remember how many pins, or what the signals are for each. That's what I'd have to look up.
In THEORY there is no difference between Theory and Practice
