My Loco runs at 1/4 speed when set at full throttle which is 12.5 volts and voltage at the engine connectors reads 16 plus volts at the same time when running. There is no noise heard when running so its not the bearings or drive rods rubbing causing any friction drag. Now when turning the engines top spindle the motor moves very freely. Also I have it pulling 8 cars with no problem but just wont accelerate at all.
