The wonderful black box breaker panel by my batteries on my 96' 215 DC does not have the breakers labeled. The two on the left and the red center one are locked in the "in" position while the one on the right is tripped "out". What does this breaker control? I am going through and replacing old original pumps, but may not need to if the breaker is bad. My bilge pump and fishbox pumps are not working and have definitely seen better days. If it is bad where do I get a new breaker to replace it? I did see some good pictures of the back of the box on another post, just not the front.
Thanks in advance for the help.
