Not familiar with this model. Just trying to get a quick area to look at. Battery is good. Fuses good. Travels fine. Will not lift at handle or grab bar. The BDI has no display except for a "stop" light. I switched harness and BDI with another good unit, but same issue. contactor jump and unit lifts. It does lower by both switches. Opened controller to check security of ribbon. No internal fuses. ???
