My '15 is now different since solar install, but only recall one small breaker in the + line from the OEM battery setup. If there is a second one, it would have to be after the + line splits somewhere as 2 breakers in a row doesn't work well. Only had one on the '05 also, small reset button on the side, hard to see.
