TM 9-2320-280-20-1 2-32. INSTRUMENT TESTS These Instrument Tests can be run any time you think there is a problem with the instruments or if you were sent here from another test. If you get an unusual gauge reading it is a good idea to check out the system that the gauge monitors to be sure that it is a gauge problem and not a real problem in the engine or electrical system. Refer to fold-out page FO-10 and leave fold-out open for reference during testing. Diagrams of the individual gauge circuits will be found on the page that deals with that circuit. 2-319
