Singer 99 Motor Help
I have a 99 in need of a motor, and someone gave me an old one which came from a 99 and which is a Singer motor. It needs a lot of help, including brushes. Before I invest I'm wondering about the wiring.
So far, all motors that I have opened up have only 2 wires coming off them, one from each brush, and I've not had any problems getting them back running and wired correctly.
This motor has 3 wires coming off the motor, one from each brush and then an extra one off one set of windings and then joining one of the brush wires, see the first picture, the 2 wires on the right, connected on the back side as seen in the second picture.
Does anyone know what the 3rd wire off the windings is for? Do I just treat those two wires as one for connecting a foot controller? If it matters, I will not be wiring a light into this mess.
