Connect the green wire from the gauge to the white wire of the water. temperature sensor. Then, connect the black wire of the water temperature. sensor to any good (unpainted) ground connection. 5. Using automotive grade wiring (18 gauge); connect the red wire to a. positive 12 volt ignition (switched) source.
The gauge requires an electric circuit and a sending unit in order to read temperature. The sending unit is a temperature-sensitive material that is part of a variable resistance, water-sealed unit that sits in the coolant stream in the engine. As the engine warms up the resistance in the sending unit is lowered gradually until the system reaches maximum heat. The sending unit is the ground portion of the circuit. In the completed circuit the battery voltage passes from one side of the gauge, through the bimetallic spring and onward to the sending unit, which is grounded to the engine.
