Kone Resolve 20

We just took over 4 resolve 20s with Yaskawa drives. One car in the Up direction pulses and you can watch the amp draw go from the 40s up to 80s as the car runs this is constant pulsing in high speed. The car runs fine in the down with a every even amp draw. Anyone had this problem or have a good start on what to look at. I'm sending weights to see if this affects the problem.

Sounds lke the overcharge resistors are open.
