Coolant level indicators can operate differently on different vehicles. Not sure about yours? I have seen level sensors that would turn on the lite if disconnected. If I understand the wiring on this, there should be no continuity between terminals B and C on the sensor itself. Is there is heating element on the sensor?
In the diagram the yellow wire is voltage, black is ground.
