Singer 66 Motor Odor
My husband surprised me tonight by redoing the wiring for the 66 (it usually takes him months or years to do the things on his honey-do list). Prior to him redoing it, and also since it's redone, the motor puts off an odor. Is not really a burning odor or anything like that but I don't quite know how to describe it. Is this a sign of something not being right? It's a Universal motor. My husband is Googling right now and found something about brushes inside the motor burning on cheaper motors. I am dying to do some sewing with it tomorrow but I don't want to cause damage if this is a sign of a problem.
