Does Multiplus 3000 12v need case ground to work?

So i get 14.35 or so when it switches to charger mode at case posts out to batt.

But, at batt terminals it reads whatever charge its at. Meaning whatever solar charged it to. Dusk = 12.35 or so.

Meaning i dont see spike at batt terminal to relate to case posts.

Checked wiring double or more. Still at batt post out to studs it reads current value

??????????

thx
