Ok, so the wife's car randomly shut off this morning. Checked the battery and the positive side was just a big pile of corrosion. Took everything apart and cleaned the terminals, vacuumed the mess.
The inside of the positive terminal was actually corroded away, so much that you cant tighten it back on.
What's the deal with the explosive device? Can i just get a generic terminal and put on amd leave the two black wires unhooked?
