The voltages measure as follows: 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 resistance between J-1 and J-2. The resistance measures between 7.5 and 10.5 ohms. If incorrect replace the motor. If correct, replace the system board. 2-64 Service Manual

measure as follows:
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
resistance between J-1 and J-2. The
resistance measures between 7.5 and 10.5
ohms. If incorrect replace the motor. If
correct, replace the system board.
