I would pull the motor and check all of the wires as best as you can. If the blak heat shrink moved up then that could be a likely problem spot.Hopefully somebody will chime in that knows how to remove the rear endbell. That way you could get a better look and fix if there is a problem. If you have an Ohm meter you could check if there is a short between the wires and motor. That would be the easiest way without taking everything apart.
