another technical manual and the procedures can be directly referenced. When more than one
level of maintenance must be provided for, organizational- and intermediate-level troubleshooting
procedures shall be separated so that the organizational-level troubleshooting procedures are
identified as "Organizational-level troubleshooting", and are presented first. Intermediate-level
troubleshooting procedures shall follow organizational-level procedures and shall be identified
"Intermediate-level procedures". Immediately following this title the following statement shall be
included: "These procedures are authorized for accomplishment by Depot-level activities only."
When a separate depot-level manual is specified in the TMCR (see 6.2), it shall include the
information required by MIL-DTL-24784 and MIL-DTL-24784/7.
3.6.6.1 Troubleshooting instructions. This chapter shall contain all instructions and information
necessary to locate troubles and conduct tests on each component, assembly, or subassembly of
the equipment as follows:
a.
Troubleshooting guides providing step-by-step procedures for logical isolation of faults. This
information shall direct the technician to observe meters, fuses, circuit breakers, valves, and
other available indicators which would indicate the presence of trouble.
b.
Complete instructions on signal tracing for electrical circuits including the use of special test
instruments and unusual servicing techniques.
c.
Where appropriate because of equipment complexity, troubleshooting diagrams (in
accordance with MIL-DTL-24784) including schematics giving details of mechanical and
electrical assemblies and relationships as follows:
1.
Mechanical schematic diagrams.
2.
Piping diagrams.
3.
Control diagrams.
4.
Power distribution diagrams.
5.
Maintenance schematic diagrams.
3.6.6.1.1 Diagnostic analysis. This chapter shall also provide guidance regarding
diagnostic analysis of possible trouble situations wherein malfunction, fault or failure of this
equipment or related equipment could render this equipment inoperative or unable to fully
perform its intended function. This information shall direct the technician to observe lights,
gauges, meters, fuses, circuit breakers, valves, and other available indicators which would indicate
the presence of trouble. Kinds of troubles to be dealt with include, but are not limited to, the
following:
a.
Low lube oil pressure or loss of oil supply.
b.
Out-of-tolerance voltage, power or current (input or output).
c.
Out-of-tolerance temperatures (input or output).
d.
Out-of-tolerance vacuum (input or output) evaluation tests.
e.
Out-of-tolerance regulation of (or inability to adequately control) speed, load, voltage, current
or fluid flow.
f. Fluid leaks which endanger personnel or functional adequacy of equipment.
g. Valves or fittings stuck in off-design or nonoperative positions.
