do you have time to continuity test from the meter box to the panel box to see if they are isolated?Neutral removed:
Water to railing: 2.1VAC
Water to deck: 1.35VAC
Railing to deck: .56VAC

If you attach a wire to the ground rod which we know goes to the panel and take it with a meter. One lead to the wire and the other lead into the ground and test for voltage. This will work much better if you know the route the incoming feeders travel.Seems like the voltage is probably not coming from the house side.
Maybe an exposed wire connection underground on the main incoming hot wires?
That would be difficult to check.
Maybe a signal generator on the main incoming power wires to see if it shows up on the oscilloscope?
since there is continutiy with the neutral lifted that means the neutral is not out of the running.Continuity between panel and meter box
Voltage differential between neutrals:
117mV AC
160 - 260mV AC from ground to meter box.If you attach a wire to the ground rod which we know goes to the panel and take it with a meter. One lead to the wire and the other lead into the ground and test for voltage. This will work much better if you know the route the incoming feeders travel.
On a super busy highway, maybe 300 feet? I really don't know because we don't have anything in our yards.With the neutral disconnected, the current would not be able to get back to the transformer neutral through the wire and it would need to go through the ground to the transformer ground rod.
How far away is the transformer from the house?
