With the weather being what it is today, I'm staying indoors. My recently acquired vintage watch cleaning machine kept blowing rheostats. The guy I bought it from had rewired everything underneath, and after checking everything it all appeared good. I ended up finding an issue with one of the wiring connections inside the motor, which was holding on for dear life. I did a little bit of maintenance work to the motor, and then rewired it. It's running beautifully now.
