Electrical problem 12 v
2014 25’ FB FC. Put trailer away last fall with no problems. Removed batteries and put on trickle charger. Installed batteries this evening. Not on house power. Power jack light works and jack functional. Propane detector light on. Inverter remote switch powers on. But I have no cabin light, no + water pump, no stereo, no monitor lights. What am I missing? If it were a blown fuse somewhere in the trailer would the propane leak detector light up and inverter work? Thanks for any help.
