sewbizgirl, What does it usually mean when an electric machine starts running the moment you plug it in? I've seen a few of those lately. What's the fix for that? Total re-wiring
That is what is going on with the one I just posted a link to above!
Billy worked on a Brothers 1961 for me and when I got it back and pugged it in, mine did the same. I found out that I had the plug reversed between the electric and the foot pedal. Try reversing the plugs.
