	Assembly High	capacity system board. The voltages
	Capacity Feeder	measure as follows:
	System Board	Static (Motor Not Running)
		J1-1 (Brown): approximately 0 V dc
		J1-2 (yellow): approximately 0V dc
		Motor Running Forward
		J1-1 (Brown): Approximately 0 V dc
		J1-2 (Yellow): Approximately +24V dc
		Motor Running Reverse
		J1-1 (Brown): Approximately +24 V dc
		J1-2 (Yellow): Approximately 0 V dc
		If any of the voltages are incorrect,
		disconnect the motor and measure the
