30amp Battery to Junction Box Fuse - LOCATION

[killerRV]

Have a 2016 Jayco Jay Flight SLX 264BHW. Battery will not power interior lights, awning, etc. Worked perfectly for the last year until now. Had the battery tested and it is good and charged. Terminals/wires are clean and snug. When hooked up to towing vehicle or shore power everything works fine.

All fuses on the panel are good.

Is there a fuse between the battery and the junction box somewhere? Can't seem to locate it.

Typically the dealer will install a 30 amp fuse at the batter. Check for that fuse, use a multimeter, sometimes the fuses can pip and you can not tell visually. Also check the connection at the battery. Also check the ground wire from the frame to the battery, could be broken or corroded. Also double check for reverse polarity, and the fuse for it.

On my 264bhw there is a marine grade blade fuse holder with a 30 amp fuse placed inline just before power cable enters trailer. I am unsure if this was from factory or dealer installed.
