Learn from my mistakes, mistakes in troubleshooting! I should have comprehended and listened to C.Martin early on in my discussion with him on this issue, he was spot on, for that I paid a steep price.
I ordered another BMV 712 from Amazon ($200+) as I couldn't find just a shunt or board option. It came today so I decided to just replace the board and not deal with the shunt and go from there. Yep, that didn't work. I replaced the control head/display - no luck. Bad UTP cable? I connected the new cable to the new control head, no luck.
Yes, I paid over $200 for a FUSE! Replacing the "expletive" fuse in the temp probe solved the problem. Here is Charlie's initial diagnosis of which I didn't believe was the issue.
Quote:
The temp probe attached to the BMV is a combination device. The red lead with inline fuse supplies dc+ power...the black lead transmits the temperature signal. The unit gets it's dc- from the 4/0 black cable attached to it.

Let me also add, as usual VICTRON ENERGY is of very little help when emailing them. They're dismissive and brief, granted, English is not their first language either. But I received no educated guidance from them such as check the fuse! I will figure out who my local dealer is and go to them next time or PKYS.com is probably a good place to get help and parts.
So with that said,
click here and order spare fuses. Your BMV 712 kit comes with two temp probes so if you want to carry the spare probe or fuse from it with you that would get you a spare too. Mine is back at home as I'm on the road.

P.S. Will I be putting my shunt in a IP box? NO. I have a spare now obviously but to date it's endured the elements. I'll work on designing and 3D printing one for fun but for now I have no desire to deal with the shunt.
