touched the trim ring around the shower valve and felt a slight shock.
After I finished, I got my multimeter and measured 7.5 VAC from the trim
ring to the shower drain fitting.

Joe,
I think there is some confusion. I’m also guessing that you did not follow
the link and read my more detailed blog
The question of eliminating the ac-dc ground connection if an ELCI is
installed is an interesting one and I'm glad that Paul brought it up.
There's no question that isolating the ac green wire ground from the boat's
dc ground system will eliminate dc current flowing through the shore power
system.
Joe,

reaction, I would have reacted the same way a little while back.

I disagree with this.
I have had a galvanic isolator since about 1995 or so. Mercury Marine sold them
to keep their outdrives from dissolving back then and I grabbed one. I can go
on for a while about how they work, but the short version is every boat at the
marina is wired together by the groun
