The thick wire on the left side of the shunt goes to chassis ground. The battery negative is connected to the right side of the shunt. |
Oh yes! A senior moment - I didn't even read the excellent labels...

PSA:
My driver side 'house' battery box has no "drains." any moisture that goes down there, at least in my case, stays in there until it evaporates.
If your house battery box is also like mine, consider adding weep holes, or such.
Finding this out, in my case, was NOT FUN AT ALL. Most likely I spilled a flimsy cup of water below my left elbow backwards, and the liquid ended up in the box with nowhere to go. However, I am not 100% sure I actually did that, it is just the only explanation I have for a self-caused inch or so of water down in there. I had also, in the same time frame, driven through some of the worst sloppy wet 7" snow storm I have done in my bus, and there could have been another way for liquid intrusion. It was water, not tea, and those are the only things I drink while driving.
