Can someone please tell me the name of this part and exactly what it does? It's corroded and I want to replace it when I install the new battery. It's connected to the positive terminal wire. Thanks!!!

That is an auto resetting breaker. Kinda like a fuse that doesn't burn out but instead it resets itself. You can get them at any auto parts place and they're inexpensive.It will be marked with its current rating.

its called a inline fuse, some where on it there should be a marking for how meny amps it is,and can be bought any any auto parts store , you could follow the wire and see whats hooked up to it.

I'm sorry but that's not a fuse.It's a breaker and even though it says "Batt" on one side, it is not polarity conscious. They just mark them that way to keep the questions down.

Not a fuse, it's a breaker. Take it with you to any auto parts place. Not only do they have different amps but they have some with different size lugs also.

Definitely an auto reset circuit breaker. And as mentioned, inexpensive. Or maybe cheap is a better description.Here is what one looks like inside. This one burned the contacts.

Won't the onboard fuse panel blow a fuse before anything fries ??

No. The dash fuses only protect the circuits they serve. Bypassing this breaker would negate protection of the circuit it serves, possibly the main battery feed.

I'm going to use the beloved (or hated) water pipe analogy here. Think of the water supply at a sticks & bricks house. If the only shut off valve was located 30' inside the building and the supply pipe breaks before that valve, how are you going to keep from getting flooded?

So, from your example, what is of concern is the wiring from the battery to the Fuse Panel. Guess I should try to find a part number or specs and wire up a new one.....Thanks

Smoke and fire when you short a wire.

rather than trying to clean the end of the wires, replace them too.
