Coolant Temperature Gauge: Description and Operation
When the ignition is in ON (II) or START (III) battery voltage is supplied through fuse 13 to the gauges in the gauge assembly.
Engine Coolant Temperature Gauge
The engine coolant temperature (ECT) gauge is operated by two intersecting coils wound around a permanent magnet rotor. When voltage is
applied to the coils, a magnetic field is generated which causes the rotor to rotate and the gauge needle to move. The magnetic fields are controlled
by the engine coolant temperature (ECT) sending unit. As the resistance in the sending unit varies, current through the gauge coils changes, and the
gauge needle moves according to the changing magnetic field.
