@hal_pomeranz If I use an outlet tester, open ground. Multimeter - hot to ground pin, 0v. Hot to box, 0v. Hot to neutral, 120-ish volts.
There are no grounds anywhere.
In fact, we had a major hazard here when a fault at the pole sent current down the coax, and since the grounding points for the coax connect to nothing, it was just live. I was the victim on that one!
