Has anyone had to replace the Kato Coreless Motor in a FEF3? If it does start up in forward and the loco stops, it usually will not start up again in either forward or reverse. It is DCC with a Tsunami Decoder. When the throttle is opened up, the sound increases but the motor does not rotate unless you give it a kick start on the shaft. The moto does feel like it has rough spots in it resulting in vibration. The whole loco is completely apart but the motor is still connected to the tender and dcc controller. It is definitely not a mechanical bind. Thought it might be BEMF settings but the vibration in the coreless motor leads me to think the motor is shot.
