Today i swapped the current sense board from the spare VLT6042 to the VLT5042. The PCBs are similar enough but the current reads about 2x as high. The current sensors must be different in each board. Damn. I am awaiting a call from Danfoss to see if the drive has a different setting for different current sensors. Its a long shot I know.
There was a resistor array on the VLT5042 current sens board that was in a socket. I have soldered it in in case it was loose.

Still Broken?
The vehicle drives now with a different current sense board. I have soldered some connections on the original and need to swap it back on the weekend.
