Oil Pressure Gauge: Testing and Inspection
Oil Pressure Gauge / Oil Pressure Switch Test
With Fuel Thermometer SST 49 0839 285 attached to the oil pressure switch connector and the ignition lock cylinder in the ON position (engine not
running), set SST to infinite resistance. The center line of the pointer should fall on or below the "L" mark.
Short the connector directly to engine ground. The centerline of the pointer should fall slightly above mid-scale.
