Finally getting around to working on some of the machines and this is the first one that is giving me fits. Plug it in and it goes, full speed. The foot controller doesn't affect anything. I know I've read about this problem before on the forum but I wasn't finding it and the sewing machine place closes early today if I need parts so I thought a direct appeal rather than further searching was in order. Anyone have any ideas? The wiring looks good but I haven't pulled the foot control apart to see what's inside of it yet.
