G, I wonder how you know you need a new one? Especially since you don't know positive from negative. It makes me skeptical. I say that in the nicest way! I would check it for you, if we lived close by.
But, if you really do need a new one. First, read the side and order that same ampere rated breaker. I have seen them from 5 to 50 amps. And order the same size.
It is my understanding that they automatically reset, but I had one on a boat that had a manual reset that had to be pushed in (on the side of it).
The negative side of the battery should run directly to the frame and should be disconnected FIRST at the battery end before working on or replacing this breaker.
The corrosion you mentioned is more than likely the cable ends that might need to be replaced / remade.
You will also notice the breaker has a copper and a silver colored terminal, the battery ties down on the copper side and the load (aux) ties down on the silver.
The Series 12X Shortstop Circuit Breakers feature an auto, manual and modified reset and is a single pole thermal type breaker.
