The long bus bar does bother me a wee bit, particularly if the are relatively high current devices landing a ways up the buss from that shop made bar connecting the bus bar to that plate the incoming green marked static cable is connected into. But lets start at the top of it, with all the supply breakers open, and disconnect each of the green wires in turn to check the ohms from the disconnected wire to the big plate. I would investigate anything less than say 15 ohms because it is getting a ground someplace else besides where it is intended. What is in that woven shield under the left flange? That also should be kept away from box contact except a jumper to the bus to ground it. So if you have a ground jumper from it to the bus bar, disconnect the jumper and check it too. You may have to wiggle it around a bit I insert a layer of scotch 88 between it and the box, and some of that nylon hole edge liner where it goes through holes in the box, that and make sure it is not being used as a ground at the far end of it. No shielding should be connected anyplace but at this bus. Keep us posted on what you find Sam, please?
