Temperature Gauge: Description and Operation
-
When the ignition switch is turned to the "ON" position, the engine coolant temperature gage is activated.
-
When the engine coolant temperature is high, the unit's resistance is low and there is a great flow of current in the "H" area.
-
When the engine coolant temperature is low, the unit's resistance is high and there is a small flow of current in the circuit, so the gauge's indicator
indicates in the "C" area.
