Central Vac Circuit Board Question

[blane]

Hello All,
My mother in law Beam SC375C central vac has stopped working. I am going to change the circuit board. When I went to remove it the ground wire was not hooked up. I hope someone has a schematic or can tell me what terminal the ground wire goes on. Other than the ground there are only two other wires and a plug. Any help is appreciated. Thanks

The ground wire goes on the middle terminal between the two black wires.

Depending on its age/use, it might make sense to have a new motor on hand too. They go out more often than the boards, in my experience.


Hope this helps!
