I think my American flyer 401 has a motor short...
Engine needs a lot of power to run and gets very hot.
I am assuming that the short current is relatively high (put not high enough to trip the circuit breaker), with the current actually going through the motor being low. Once the voltage gets high enough, the current that actually makes it through the motor (and not the short) causes enough motor torque to overcome static friction in the motor. The part thats shorted contributing to the excessive heat.
Am I analyzing this right? If so, should I look to get it re-wound or replaced?
