and the engine {ground). There should be continuity
with the engine stopped. There should be no conti-

Start the engine. Shut it off immedjately if the gauge
registers no oil pressure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (fan
comes on at least twice). The pressure should be:
