12 volt does'nt work
i have a 2022 Forest River Flagstaff 21FBRS travel trailer. In 4 years we never had an issue until now. On our last trip, our 12 volt system stopped working (fridge, slide outs, lights, etc.). I made sure that the the battery disconnect switch was on. I checked circuit breakers. All okay. Once we got to our destination and plugged into shore power, everything worked. When we got back home I had the batteries checked. They were bad, so I bought new batteries. Still no 12 volt working. So I assume the problem is somewhere between the batteries and the the inside of the trailer. By the way, I tried the electric jack using only battery power and it works just fine. But I guess that is because it is directly connected to the batteries. Any suggestions on trouble shooting before I take it back to the dealer (which charges $165 per hour).
