I have a Dover T4 that had the C1 contractor meltdown. It caused a lot of problems. I have since replaced the contractor, DSP board, Gate Driver board, various modules etc. My problem now is that when I tried to run the car down on inspection. It drifted into the overhead. When I try to run down now. The brake picks and the motor tries but can’t lift the counterweight. After a few seconds it faults out on 626 fault code. No LED’s are lit on the GD board and the contractor is new. Also I have 626 VDC on the DC buss. Any recommendations would be greatly appreciated. Thanks
