A bit more info would be helpful:

Do the lights stay on when the engine hum stops??

Is the motor part of the front or rear truck assembly, or is it a can motor with drive shafts going to the trucks?

If you apply power directly to the motor, does it run okay?

Did you accidently connect the track to the AC accessory terminals on your power pack??
