Posted same thing a couple of weeks ago, there is a "breaker" that in my 2016 Quantum is located in the coach battery compartment. The breaker has a yellow flag that is kicked out when tripped. The fun part was locating this breaker, with the help of other forum members, I found it on the forward wall of the battery compartment tucked up near the top. I had to crawl underneath the RV to be able to see it. The attached picture was taken after I reset the flag.
