I had a 1989 Ford Ranger from the city of Santa Rosa that was converted to electric somewhere around 1994 in Grass Valley. It used the 120V variant of the GE forklift drive. Service manuals were not easy to dig through, but in my experience, there is very little that goes wrong with the controller card unless you miswire something. My only failures were blown (shorted) IGBT and freewheel diode. That will be detected by the controller card as voltage out of range during initial startup, because it will test for voltage present before closing any contactors, then try to pre-charge the power stage and verify that the voltage is doing what it is supposed to do (go from min to max) and only then it will close the big contactors to drive power. It is easy to verify with a multimeter if there is any short on the switching transistor and diode. Also you can follow the test wiring from the output stage back to the controller card. Compare to the service manual. I hope this helps, let me know if you have further questions, Cor.

The manual was huge. A little hard to understand. Some how I got it running. Loved how it drove. However it seemed inefficient. The motor/controller was noisy. What voltage are you running? Do you have a 12 volt battery? As an option you might think about a Curtis type controller. Up running in short order.
