P.S. Whenever I see a wonky voltage with the trailer or the van I always check it with a trusted meter.
P.P.S. You don't have any grounds on the upstream side of the shunt, right?

I think that's the ticket, test it and see what happens. Your batteries are probably still covered under warranty so you could go that route if they fail your test. The Aili meter on my mini battery has never reset itself, but I don't use it very often. I was going to ask if maybe you fat fingered the buttons and reset it while you were freaking out over your low voltage but after looking at mine again I don't see how you could do that. Logic diagrams for trouble shooting my own technical issues *always* start with "Did you F with it?"

I just had a thought. It's a long shot but put a meter lead on the positive battery terminal and one in the dust on the battery. If there's any voltage showing then the dust could be conducting across the terminals that wouldn't show up on the Aili meter.

Never underestimate Gotham City. People get mugged on their way home every day of the week. Heh, sometimes...sometimes things just go bad.
