I spent half the cleaning and polishing. I removed the knee activated foot pedal and associated wiring. The only thing saveable was the foot pedal. I then took a real good look at the motor and decided to remove it for a thorough outside cleaning. It was then I noticed the bare wires coming out of the bottom. I was so hoping that the motor was good, not. There were bare wires inside of the motor also and did not look safe to me, aargh. Even though I really wanted to keep the blue cased motor on the machine, it is not going to happen. I guess this girl will get a black replacement motor.
