Second, operate the tank, if necessary, to verify the symptom and
make sure there was no error in the crew troubleshooting. When you
troubleshoot at this level (organizational maintenance), you assume
the tank crew performed all -10 troubleshooting correctly and
verified the fault, but operating the tank will confirm this.
b. Find the Procedure to Locate the Problem.
Once you have
identified the symptom, you must find the correct troubleshooting
procedure. TM 9-2350-264-20-1 contains a listing of symptoms indexed
by the tank's systems or subsystems. Use the symptom index to find
the tank's system that has the malfunction. The index directs you to
the starting point for the troubleshooting procedure.
Fault Symptom Index.
The TM fault symptom index may not have the same exact wording as
your symptom. If this happens, you must find the symptom that most
closely resembles the symptom you have. If you cannot find a symptom
that covers yours, notify support maintenance.
Before you start any troubleshooting procedure, be sure you
have the tank parked, parking brake set, engine shut down, and
the VEHICLE MASTER POWER turned OFF.
