IIRC It's grounded when coolant is full. Open sets off the buzzer.

The wire is not grounded to the radiator itself for the radiator housing should be plastic. The wire is part of the sensor for low coolant so the wire is connected to the sensor and it might appear that it's welded to the radiator when it is actually not.
