6.11. Testing Membrane and Faceplate
When a treadmill with a membrane experiences a loss in power to the upper display, such as when a customer
presses the START button and nothing happens, a possible cause of this is a bad membrane panel. A membrane
panel bypass test can verify this.
Note:
+12-17Vdc must be confirmed across the black and green wires at the upper connector on the wire harness to perform
this procedure.
Tools Required:
• Cross tip Screwdriver
• Digital Multimeter
• Jumper wire (only if the multimeter doesn't have a continuity setting)
1. Unscrew the three screws holding the magazine rack and remove rack.
2. Pull the display down and forward of the Velcro seal and then disconnect the membrane ribbon cable.
3. Set the voltmeter to continuity and touch the two test leads together to make sure they beep, indicating a short.
Using the jumper wire, short START (pin 15) to GND (pin 1) on the upper board as shown in the following figure.
