TM, however, uses the same flow chart organization, with cross-
references to prior and later blocks, to describe each procedure. To
familiarize you with the TM's general organization before giving you
an actual troubleshooting procedure to follow in part B, this lesson
will describe each type of block you will encounter in the fault
isolation flow chart.
Appendix B of this subcourse contains an
extract of TM 9-2350-264-20-1 giving the fault isolation process for
troubleshooting TSS-1, "the tank will not move in forward or reverse
ranges." Take a moment now to look over appendix B, in order to
follow our discussion more easily.
NOTE:
The following call-out numbers refer to figure 1-2.
a. Fault Symptom (1).
This gives the fault symptom number and
description as referenced by the symptom index. It may use a general
title when the STE test set primary procedure covers two or more
fault symptoms.
b. Personnel Required (2).
The fault isolation procedure gives
this heading only when the procedure requires more than one
individual. Figure 1-2 shows this troubleshooting procedure requires
two people.
c. Supplies (3).
Under this heading, you find any supplies or
replacement parts you must have to perform the troubleshooting
procedure. Additionally, this heading gives you the location, in the
TM, where you can find information on the supplies and repair parts
(i.e., item 77, Appendix C).
The example shows that you must have
wiping rags (item 77, Appendix C) on hand to perform this
troubleshooting procedure.
d. Equipment Condition (4). This heading gives special equipment
condition(s) you must meet prior to starting the troubleshooting
procedure.
The example tells you that you must have the main gun
positioned over the rear deck of the tank and, in the Note, informs
you to notify your supervisor that you will be working in the turret
area.
Below we list additional standard equipment conditions that the
troubleshooting procedure does not list; however, you must meet these
equipment conditions each time you prepare to troubleshoot the tank:
Park the tank.
Set the parking brake.
Shut down the engine.
Turn OFF the VEHICLE MASTER POWER.
