I have a singer 15-91 that I wanted to try and clean up to use as an alternate machine. I'm trying to decide if the wiring really does look okay, or if it's just wishful thinking, and I was hoping someone might have advice for me. It seems to be very flexible and is not cracked at all. I unscrewed the terminal, but I didn't know how to get at the motor. I'll put up some pictures as well (not very good ones, I'm afraid), but if anyone wouldn't mind giving me any tips or opinions I'd be very grateful.
