Temperature Gauge: Testing and Inspection
Temperature Gauge Test
Coolant Temperature Gauge
Disconnect terminal from temperature sending unit on engine, then connect test lead of tester C-3826A to terminal and second test lead to ground. Place
pointer of gauge tester on E position and turn ignition switch to the On position. The temperature gauge should show C plus or minus 1/8 inch.
Place pointer of tester on the 1/2 position, the gauge should advance to the operating range left of 1/2 position of the dial. Place pointer of the tester in
the F position, gauge should advance to H position of the dial. If gauge responds to test correctly, but does not operate when terminal is attached to
sending unit, replace gauge.
Multiple Gauge Inoperative
Temperature Gauge Pins - With Tachometer
Temperature Gauge Pins - Without Tachometer
1.
Remove temperature gauge assembly from the cluster.
2.
Check for continuity in wire between temperature sending unit and gauge (sensor input pin).
3.
With ignition switch in On position, check for battery voltage across B+ pin and ground pin.
Multiple Gauge Malfunction
If the Temperature Gauge, Oil Pressure Gauge, and Speedometer appear to be malfunctioning, remove the cluster assembly and check the
following:
1.
Check for good contact between the wire harness and the printed circuit board.
