My treadmill Astar TD-1600CE was plugged on the wrong voltage. It was designed for 110 Volts and accidentally plug on to 230 Volts. Searching from this forum I found this http://forum.allaboutcircuits.com/threads/pwm-for-treadmill-motor-control-board-td-1600.48582/ but does not mention about the burned resistor what I am looking for. The resistor is supplying voltage to a step down transformer that supplies the control display. Can anybody please advise on what is the value of this resistor and at what wattage?

 

Any drawing so far for this model. The drawing on the forum does not show series resistor on the transformer power supply. I have tried to put a resistor of 260 ohms 5 watts and tested the output voltage of the two transformer to be 12 and 20 volts. Is that ok? I will test it in the treadmill to find out. Any information will be highly appreciated.
