My chainsaw won't run the motor at all so i took it apart and tried replacing the switch. That didn't work. I wonder if there is a fuse on this unit or the whole motor controller is bad? When i put in a battery and press the power level button on the battery it shows zero bars. i remove the battery and it shows 3 bars. Something is causing the battery to short out?
For model number RY40502
