I have a 2015 Big Country 3950FB with a storage compartment behind the hitch ball. Opening the door provides access to the breaker area. After locating your battery bank, look on the wall directly behind them and you should see 5 breakers. Now mine have red breaker covers that are removable and they are wall mounted like rungs on a ladder one above the other. These breakers have a rectangle shape with two threated posts and each with a nut and small spacer. Amp size is on the back. Wires lead in from the right side to the right pole and electrical wiring do the same on the left side and work their way up to your controller module. Usually the very bottom breaker has a reset button located on the end of the breaker. It is the only one in my set up. Test your breakers but be careful and if you need to replace one or more, then turn both batteries OFF using the battery on/off knobs and then proceed.
To the left of those breakers is a master bus breaker with cover. Peal back cover and find the breaker size{mine says 100 amps, although their manual states 80}. Using that reference I have changed my breakers to 50 amp and ordered them from Heartland parts. I keep about 3 extra. The reset time on the breaker after it overheats sh/be roughly 5-7 seconds and not 20.
You can read your battery voltage at anytime by turning on your inverter and reading te dial, which will be on the bottom, then turn it back off.
The more that breaker cuts off, the weaker is gets so it will occur more often.
Remember: yours may be totally different or maybe kinda sorta like mine, so be patience and check it all out.
