2015 Big Country 3650 RL. No power unless plugged into shore power or on generator. The battery has been checked - fully charged - good. Checked all auto-reset fuses - they are all good. Technicians have told me there is a fuse inline that is blown. Where is this fuse located? Any other suggestions?

Hi jas8796,
If your interior lights and other 12V systems work when plugged into shore power, but don't work when shore power is disconnected, the 12V mini-circuit breaker that sits in between your battery and the fuse box has tripped. It's usually a manual reset breaker with a teeny-tiny reset button. Another possibility is that the battery cutoff switch is OFF.
Here's a picture of the manual reset breaker that's on the buss bar near your battery.
Also attaching a picture of the buss bar and mini-circuit breakers. Sometimes they're covered with a rubber boot. Yours could look different; the configuration varies by trailer model and floorplan.
Our owner-written 12V Block Diagram and Diagnostic Guide explains this problem in detail and also provides a diagnostic flowchart in case there's something else wrong.
