The ground wire in my machine is just laying there and it appears to have been torn. Maybe happened when machine was transported with back box on cabinet, but I can't find where this connects. I think it is supposed to connect to back box? Please see pix. I'm about to put in new playfield, but trying to clean inside up and get things in order. Any help would be greatly appreciated!

It's odd, it is clearly not long enough to get to that screw, so will have to extend it somehow. What are the ends ultimately connected to?

I looked closely, this wire goes through a radio noise filter, which is also where the power plug comes in from wall, then goes to front of machine and appears to be connected to almost all metal items inside the cabinet.

The back box has a braided ground going all the way across, left to right, connected to the metal sheeting on both sides, so I guess this would provide grounding for everything in back box, if it were also connected to the wire in the cabinet.

Is that it? Is that all it takes to ground the machine? Thanks again!

There is no ground going to the back box, so this must be it. Question: should all 4 legs be grounded?
