INTRODUCTION
MALFUNCTION/SYMPTOM INDEX
The Field level troubleshooting Malfunction/Symptom Index (WP 0005) lists common malfunctions found during
Field level maintenance of the 100 kW Tactical Quiet Generator (TQG). Identify the malfunction/symptom that best

TROUBLESHOOTING PROCEDURES
malfunctions, that are followed by corrective actions required to return the 100 kW TQG system to normal
operation. The troubleshooting procedures cannot list all possible symptoms or malfunctions or the tests and
inspections required for corrective action. If a malfunction is not listed or is not corrected by the listed corrective
actions, notify your supervisor. Before using troubleshooting be sure you have performed PMCS.
The work package INITIAL SETUP outlines what is needed for the task as well as certain conditions which must be
met before starting the task. Don't start a task until the following conditions exist:
1.
You understand the task.
2.
You understand what you are to do.
3.
You understand what is needed to do the work.
4.
Ensure that you have the correct manual, all related manuals, and test equipment.
The work package troubleshooting procedures have three divisions: SYMPTOM, MALFUNCTION, and
CORRECTIVE ACTION. Note that the SYMPTOMs are first listed in the Malfunction/Symptom Index (see WP
SYMPTOM: Symptoms are the indication that the generator set is not operating properly or at peak performance.
The symptom can be an electronically displayed fault code, an alarm or shutdown of the generator set, a visual
observation or a sound. Symptoms tell you that there is a problem.
MALFUNCTION: The malfunctions cause the symptom. In the troubleshooting procedures MALFUNCTIONs are
presented in order of the most likely cause for the SYMPTOM. MALFUNCTION troubleshooting procedures should
be performed in the order in which they appear.
CORRECTIVE ACTIONs are actions intended to correct the problem. The CORRECTIVE ACTION consists of
tests and inspections and any steps you take to isolate the malfunction. A test or inspection leads to a corrective
action. These are the "if" statements that tell you what to do when the malfunction is not fixed. For Army, corrective
action is accomplished by submitting a 5988E to the TAMMS clerk and the clerk processing a job order, with the
unit or direct support (Field Level) maintenance team. For Marine Corps, corrective action is accomplished by
submitting a NAVMC 10560. For Air Force, corrective action is accomplished by submitting an AFR 66-1
maintenance reporting form.
Repairable LRUs or secondary repairables (for Marine Corps) shall be turned-in, in accordance with official supply
procedures.
