I used to race a rotary Mazda Pro ET door car, and if you didn't keep an eye on the pH of the coolant, it would literally eat a hole through the engine. The engines are even built like a battery- cast iron front plate, aluminum rotor housing, cast iron intermediate plate, aluminum rotor housing, and cast iron rear plate, all filled with the same coolant.
He's got a cast iron engine connected to an aluminum radiator by two rubber hoses, filled with the same coolant.
My money's on the pH of the coolant.

That's what I'm thinking, it is chemically making voltage. Just not sure if "battery disconnected" means all batteries removed rather than just a positive or negative cable disconnected from the big one.
