No 12V power from battery when disconnected from shore.
I'm having a power issue with my 2015 26BH and was having trouble finding related issues with search, so here it goes.
When disconnected from all shore power, except the battery, my power meter tells me there is 0 charge and nothing will turn on. Actually, when I disconnect from shore power I maybe get a minute of battery power.
When connected to shore power, the inside battery meter shows full and all power items work.
When connected to the tow vehicle, the brakes work, but the 12V batter still appears dead to anything inside the trailer.
I've checked the 12V battery with a volt-meter while disconnected from shore and TV and it shows 12.67V which I believe is a full charge. I tested various connection points between the batter and where the lines run inside the trailer and they as show 12.6 volts.
Where should I be checking next? My undestanding is that the 12V items in the trailer should just work if the battery has charge.
