Batteries not supplying power to trailer

[raj]

Ok, so I changed to LiFePO4 batteries on my Micro Minnie trailer 2106FBS and I also switched out the AC-DC converter/charger to the PD4655v model with the Li jumper set to Li. It charged the batteries to 94% and I thought everything was fine. Then, the power company had an outage and I noticed that nothing worked in the trailer.

My Victron shunt says we have over 12 volts but no current. The batteries test fine at the terminals, but I see 0 volts inside where the battery wire connects to the power distribution panel. I checked the battery disconnect switch and it’s set correctly.

I thought I had read something about a fuse or cutoff under the trailer somewhere. Maybe that’s what’s happening? I’ll be checking into this more tomorrow morning. It’s midnight now, so it’s hard to work on it.

Suggestions are welcome!

I continued looking on this forum and found the references to the little black square button inside the junction box under the tongue. After carefully pulling out wires and looking under them, I finally saw the little button, pressed it, and power is restored! A few minutes later, the power company also restored power to the house and trailer. I thank those who previously posted pictures of this elusive button!
