c. Isolate the Fault Using the Troubleshooting Procedure. After
you have identified the correct troubleshooting procedure, you must
isolate the fault.
Troubleshooting procedures. The TM 9-2350-264-20-1 depicts
the troubleshooting procedures as fault isolation flow
charts.
Each flow chart starts with a fault symptom you
can see, feel, or hear during operation of the tank and
then gives step-by-step instructions for finding and
correcting the fault for each symptom. The troubleshooting
procedure also uses illustrations to show the location of
test points and tank hardware. In addition, the procedure
also references Section IV, Supplementary Data (TM 9-2350-
264-20-1), which contains test equipment and tank data. To
troubleshoot the tank's hull systems use Simplified Test
Equipment -M1/FVS (STE) as Automated Test Equipment (ATE).
(This lesson uses material from Section IV as necessary
throughout the instruction.)
Alternate troubleshooting procedure (ATP).
You must use
the alternate troubleshooting procedures when you do not
have ATE.
The TM limits ATP to those procedures you can
perform
using
common
test
equipment
available
to
organizational maintenance sections.
d. Verify the Repair. Once you have corrected a fault, you must
verify that the repair you made corrected the fault.
Most fault
isolation procedures lead to the replacement of a tank component. In
such cases, the troubleshooting procedure refers you to the
maintenance manual for the procedure to replace the component.
If
you cannot replace the component at your level of maintenance (unit),
notify support maintenance.
After you have completed the repair, operate the tank to make sure
you have corrected the fault. If the tank still has a problem, check
the fault symptom index for another troubleshooting procedure and
continue troubleshooting.
2.
Standard Troubleshooting Practices.
You must perform these steps every time you use the troubleshooting
procedures.
These standard practices improve the accuracy of fault
isolation and help prevent damage to the tank and test equipment.
a. Always close all
grille
doors
and
access
panels
prior
to
traversing the tank hull.
