While I agree that the use of an ammeter could be useful, it is difficult to see the difference between now and what the draw was before the problems surfaced. What is the connection to the mechanical drive? Did something shift out of alignment? Is there a mechanical brake that has somehow become cocked or otherwise jammed? Another area that has caused problems in the past for us has been the brush spring holders. If these get too warm, they can become weak, and eventually fail, reducing the connection, creating more heat, less torque, then more heat and even less torque until it fireballs. In my experience, the motor or brush assembly are rarely the initial cause, just the victim.
