No bet, I’m sure you’re right. The question wasn’t how is it, the question is why? I found an electrician who knew what a virtual ground is and why. I guess I’m going to have to go be nice.
What 2air said may be exactly correct. Someone hooked it up wrong, and it happens to work unless you turn the battery equalizer off (which isolates it from ground, and therefore the hull). And, it’s an aluminum boat, so maybe they didn’t want the common to go to hull..... which isn’t a problem if all of the conductors are connected to equipment properly.
So you knew the how, and you have a theory as to why; what is the solution?
I will enjoy reading about how you resolved the issue; whether your electrician resolves it or you do.
cheers,
