lower control module. If the voltage readings are present, continue with the next step.
Drive Motor Winding Check
CAUTION: All resistance measurements must be performed with power removed
from the machine. Performing the resistance measurements with voltage applied
tho the circuit can damage the muftimeter.
7. Set the treadmill's ON/OFF switch to the OFF position. Disconnect the drive motor con-
nector from the OUTPUT connector on the power control module. With an ohmmeter,
measure between terminals 4 (red) & 5 (white), 4 (red) & 6 (black) and 5 (white) & 6
(black) of the drive motor connector. Each reading should be approximately 2.5 ohms. If
any of the readings are significantly high or open, replace the drive motor.
8. If the ohm readings are correct, inspect the female terminals of the drive motor con-
nector. Verify that they are not spread beyond the point of making good connection with
the male pins on the OUTPUT connector on the power control module. If proper con-
nection is not being achieved, replace the drive motor connector.
9. If you have performed all of the procedures above and have been unable to correct the
problem, call Precor customer support.
