I am hoping for some information. I have a customer with a B/T prime Mover pallet truck. The lift cuts out. When you reset(disconect the battery)it will operate till the battery indicator on the display lights up, then cuts out. The battery is ok. I suspect that the low battery cutout circuit is out of wack. Is this all controlllerd by the curtis controler? I think that the controller is the problem, but would like some confermation, if posible.(Curtis controller MD# 169072-003 S/N 1296B-018302 24-36 volts 200 amps.) Thanks. Ralph
