I REFERENCE INFORMATION TM 9-2320-387-24-l INSTRUMENTS CIRCUIT These gauges are galvanometer-type gauges. It is conceivable that the coil in the gauge may have a broken wire that only opens when the gauge is warmed up. If you are having an intermittent gauge problem, leave the vehicle running for a while and watch the gauge. If the system the gauge monitors is OK, but the gauge is reading full scale one way or the other, then you may have this type of problem. Fill the fuel tank, if necessary, to obtain a reading greater than empty. GAUGE With engine running, the oil pressure should be approximately psi kPa) psi (276310 kPa) at 2.000 rpm, it should when stopped. I Make sure shift lever is in neutral before running this test. With the engine cold, the gauge should read off scale to the left and, when warm, the reading should be 190”- 230°F (86” - 110%). OIL PRESSURE GAUGE TEMPERATURE GAUGE - 2-311
