   What you are describing are the classic symptoms of shorted turns in an   
   armature.   
      
   This is common in Rock-Olas and persistent right up to the last record playing   
   machines.   
      
   What happens is that one or more armature windings get shorted and draw   
   excessive current.   
      
   If the motor comes to a stop on good windings it may be able to start and the   
   short will only cause slower rotation and heavier current. Eventually the fuse   
   blows.   
      
   When the starting point has the brushes on the defective winding, the fuse   
   blows instantly.
