Daytona Shelby V6-181 3.0L SOHC (1991)
Temperature Gauge: Testing and Inspection
1.
Run engine until normal operating temperature is reached. Record gauge position.
2.
Turn ignition Off and remove temperature gauge assembly from cluster.
Temperature Gauge Pins
3.
With ignition switch in On position, check for battery voltage across Ignition pin and ground pin.
^
If voltage or ground are missing, check wiring, printed circuit board and connections.
4.
Connect an ohmmeter to the temperature sending unit pin and the ground pin.
Gauge Calibration Chart
5.
Compare the ohmmeter reading and previous gauge position with the Gauge Calibration Chart.
Multiple Gauge Malfunction
If the Voltmeter, Speedometer, Tachometer, and other gauges appear to be malfunctioning, proceed as follows:
1.
Remove the cluster.
2.
Check for ignition voltage at cavity 9 of the red cluster connector and ground.
^
If voltage is not present, repair open circuit.
3.
Check for ground continuity between cavity 14 of the red cluster connector and ground.
^
If a good ground is not present, repair open circuit.
4.
If circuits are OK and pins or connectors are not distorted, replace the printed circuit board.
