Testing and Inspection: Dash Gauge Test for Tempo L4-140 23L HSC
Temperature Gauge: Testing and Inspection
Dash Gauge Test
1.
Disconnect battery ground cable and remove gauge from vehicle.
2.
Connect ohmmeter between gauge terminals and read coil winding resistance.
3.
An upward movement of ohmmeter needle from 10 ohms to 14 ohms is normal, as test current of ohmmeter causes a temperature rise in gauge coil
windings.
4.
If ohmmeter reads below 10 ohms or above 14 ohms, gauge is defective.
