Q:

Follow up question on broken treadmill.... From George on broken Proform 540-S, to MMH EXPERT_JK:

A:

Thanks for sending a second email.

If the relay on the motor controller board was stuck in the on position, the incline motor would have tried to go up with the 8 wire harness disconnected.

I am sending you an image of the wiring schematic for the treadmill. If you have a volt/ohm meter, you can check the continuity of the wires in the harness to the 8 wire connector. If you read for resistance between each of the wires in the harness you should not get any resistance between any of the wires, with both ends of the harness disconnected. If you read resistance between any wires, replace the wire harness.

If the harness checks good, the console is bad.

The harness that goes through the frame of the treadmill is where the shorts usually occur.
