Nautilus 500.2 Treadmill (Belt won't move)
Elevation motor, upper panel are working. Speed sensor is 5V is constant from the speed sensor port on the controller board. Speed sensor when plugged in 0V-5V when rotating front roller past the magnet. LED light blinks when magnet passes speed sensor. Unplugged motor connectors from the board and took reading at the pins with treadmill plugged in. Getting 15VDC volts coming out of the board. Did the manual test with 18V drill battery. The motor and belt moved. I'm not hearing the relay click at all when everything is plugged up to the motor controller. Not sure what the issue can be. Please help.
