SC6500|SpecificationsShop MeasurementsShop measurements are values that were measured on a real machine. While they are not “specifications”,they can help you recognize normal vs. abnormal.Wheel Drive Controller Voltage MeasurementsAll voltages are DC unless otherwise stated and were measured with the negative (black) voltmeter lead onbattery negative and the key switch on. Battery voltage was 38.52 V at time of testing.Low Current 35 Pin Connector (X6)Pin Wire Color Circuit Voltage1 ORN Key switch input. Provides logicpower for the controller and powerfor the coil drivers.37.67 V2 Not Used3 ORN/RED Fault (Curtis Driver 4) 34.37 V with no current faults4 YEL/RED Direction (Curtis Driver 3) 34.37 V Forward or Stationary0.004 V Reverse5 RED/WHT Motion (Curtis Driver 2) 25.85 V Stationary0.005 V Moving (Forward or Reverse)6 BLK/YEL K7 Main Contactor Driver (CurtisDriver 1)37.7 V key on (contactor off)When seat switch closes, momentarydrop to 1.7 V to turn on contactor.Then stabilizes at 9.1 V to holdcontactor on.7 BLK/PINK Sensor ground reference.
