I have a 1963-ish Singer Fashion Mate Model 237 that Billy did the spa treatment on a couple of years ago. It has been sewing wonderfully but now, after I moved it from one end of the house to the other it's going on/off. I can wiggle the power cord that goes from plug-in to motor & it will come back on. Then I can sew, but when I stop it won't run until I wiggle the cord again. Somebody tell me what to do or do what Joe said & buy a new one. The "less easy way" would be a "no way" for me.
