Default Corrosion in the servo motor

Rick (the customer) is correct, and the cause was mild corrosion in the motor itself. It is impossible for us to know how it came to be corroded. Turning on the servo freed it, and if the corrosion was worse to completely immobilize the motor, the shear screw is there to free the controls when enough force is applied. Admittedly, the language on the repair type checkbox is a bit terse. "Installation Induced Failure" is really a catch-all for things that we can see a clear installation, environmental, or other explainable cause that we wouldn't attribute to a defect in materials or workmanship.
