I don't have a recommendation for you. It can get pricey. A through-shaft encoder with 150 PPR or more will start at $500 new.

There was a comment over on diyelectric that the throttle pot needs calibrated parameters to initiate the gates and subsequently turn on the igbts. May need other things calibrated also.

O'Scope would help here.

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...

Voltage on the phases or voltage between the phases? I would think between phases should be zero.

Tried to use a high impedance dvm on the gate pins? Should swing from 5 neg to positive 15, I...
