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.
