Fault Assessment Procedures.

a.

Be sure to read Chapter 2 before starting 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.

Procedures below 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.
