Here are some quick tests you can run to assess the performance degradation.
Make a test rig using a well-assembled, lubed, and broken-in dual-motor gearbox with an encoder. And set aside a known-good CIM (I'll call it the "reference CIM" with its leads soldering together. Keep this test rig for future testing and CIM evaluation.
1) Put the suspect CIM in the gearbox, apply full voltage, and measure the free speed.
2) leaving the suspect CIM in the gearbox, add the reference CIM (with leads soldered together) to the gearbox. Apply full voltage and measure the speed.
3) If you don't already know approximately what results you should be getting, remove the suspect CIM and repeat steps 1 and 2 using a known-good CIM.
