By the looks of the wood it's sitting in that was originally a treadle cabinet someone altered when the machine was electrified.
The motor, light and wiring I can see in the pic look OK. I can't see the power cord or foot controller.
Most likely their will be, or should be a cord block in the system. The power plug wire goes into the two outlet block on one side, the motor and light plug into it, and the cord with foot controller comes out the other side. Very simple and common set up.
How is that one set up?
