If he's still got voltage with everything disconnected / shut off, then it's not the car's electrical system.

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.
