Hello all,
I have a treadmill that is in great working condition, except for the console PCB. voltage diagram attached.
The power board has a troubleshooting LED that monitors the speed control signal being sent from the console. It passes through the power board and on to the PWM motor controller. The LED should flicker when speed is set above 0 MPH. It does not, and the DC drive motor will not turn. Also, the AC incline motor will not turn when incline is increased at the console. However, I have gotten the drive motor to move when I attached a 1.5V battery to the PWM speed control, and I have gotten the incline motor to turn when jumping on the console PCB.
I was hoping I could substitute for the console speed control signal with an external VDC source that I could vary to change speed. Is this possible, and if so, how would it be accomplished?
Thanks in advance for any suggestions.
