SECTION III. Fault Assessment Tables and Procedures
11-5. Fault Assessment Table and Procedures.
a.
Be sure to read Chapter 2 before troubleshooting. The appearance of an
assembly or component may indicate its general condition and reflect the type of
damage it has suffered. Examine for dented surfaces or holes, torn insulation, severed
cables, or other evidence of damage. This might indicate the source of trouble and the
need for repairs. Also check component boxes for unusual odors. After obvious damage
has been repaired, attempt to operate the communications system to check for damage
that might not be so obvious. The procedure below will direct you to a detailed
assessment procedure. The detailed assessment procedure leads to an expedient repair
procedure, if one exists, for the particular battlefield damage or to another chapter in
this manual.
