I got this Singer model 648 out of good will a few years ago and finally got a place to set it up. When I plugged in everything it still didn't work so I took a look at the plug between the step and the wall outlet and saw that 1 of the metal pegs appeared to be missing. I don't even know what to call this part if I were to describe it to somebody, and that's mostly what I'm looking for along with whether or not I could fix this or whether I'm just stuck with a brain- dead sewing machine.
