Turn treadmill off. Disconnect drive motor wires from lower control board (Mtr + and Mtr -) terminals. Power up in OLS mode (FAST & START). Bring displayed speed up to 99. Measure across the Mtr + and Mtr – terminals with your voltmeter (DCVolts). You should measure at least 90 vdc on a 110V treadmill and 180 vdc on a 220V treadmill.

If you are not getting dc volts out of the lower board, replace it.

If you are measuring the proper dc voltage out, replace the drive motor.
