The elevator moves in one direction only.

	FRU	Action
1	Stepper Motor	Check the voltages at J1 on the high
	High Capacity Feeder	capacity system board. The voltage
	Option Control Board	measures as follows:
		static (motor connected)
		J1-1 (Orange) +24 V dc
		J1-2 (Yellow) +24 V dc
		J1-3 (Green) +24 V dc
		J1-4 (White) +24 V dc
		motor running
		J1-1 (Orange) approximately +12 V dc
		J1-2 (Yellow) approximately +12 V dc
		J1-3 (Green) approximately +12 V d
		J1-4 (White) approximately +12 V dc
		If any of the voltages are incorrect,
		disconnect the motor and measure the
		resistance between pin J1-1 to J1-3 and J1-
		2 and J1-4. The resistance measures
		between 10 and 15 ohms. If incorrect,
		replace the motor. If correct, replace the
		high capacity feeder control board.
