I have a MC2100 Rev B V#37376 controller board still in a Nordictrack C2000 Treadmill. The treadmill powers up and motor spins for about 2 second before shutting down. All lights on upper panel go out and come back on after shut down. Pressing the STOP button and the START again will cause the same thing to happen.
Looking at the motor control board, the reed switch is functioning correctly. The red led comes on and stays on solid. The 5V regulator checks out. I had to create my own schematic, so if one exists for this board, that would be awesome! I attempted to short the terminals of the motor temp sensor on the board to rule out a problem there, but got sparks somewhere in the area of the micro and I decided not to try that again. The unit still behaves the same after that and I couldn't find any residue of where the sparks originated. Should I be able to short those terminals without a problem?
I'm looking for some ideas of what to look at next. I have a multimeter and I can mostly just see voltages come up and then go right back down.
Thanks!
