There is really only one way to find out, and due to the RMA policy, it is free.
To measure CIM resistance, you really need a 4 wire set up and you need to check across the range of shaft positions. Hook up the 4 wire resistance meter and SLOWLY turn the shaft in small degree increments, pausing for a few seconds each time. The brushes can easily double / halve (or more) the resistance for a given position, and the back emf (generator voltage) of a moving CIM will overwhelm the ohmmeter.
