Pete, thanks for your post, when you say "Neutral returns to source via ground " a rusty old retired Power Distribution Engineer would say it different, like this:
Neutral current normally and preferably returns to the source via the Neutral current conductor which, to protect against lightning and surges and stabilize the grid at a common low voltage earth reference, happens to be earth grounded at every few utility poles and all transformers and service entrances.
What I'm saying is the Neutral conductor carries normal return current (NOT earth) and that conductor is grounded to mother earth at several locations to reduce lightning and surge problems and, as I explain below, things can still "work" if you use dirt instead of that wire up there. The conductor returns current to the source normally but if not there sure earth can suffice to some degree but you dont see much one wire HV service out there"""
See my post below for a more detailed explanation
HOPE THIS HELPS nice post, have a great day

Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that.
