TROUBLESHOOTING
1. GENERAL
This Section contains troubleshooting information to assist in locating and
correcting operating troubles which may develop in the unit. Each malfunction for
an individual component, unit, or system is followed by a list of tests or
inspections, which will help to determine probable causes and corrective actions
to take.
The tests/inspections and corrective actions should be performed in the order
listed. Troubleshooting is a logical and systematic process of determining and
correcting the cause of a malfunction. The process begins with verification of the
malfunction. This may involve an operational checkout of the unit. After the
trouble has been verified, identify all components in the circuit whose failure
could cause the symptoms observed during the operational checkout. The
technician should start by checking those items with the highest probability of
causing the problem. Inspect and test each component, until the exact cause of
the problem is determined and corrected.
