M2/M3 BFV: TROUBLESHOOTING - OD1610 - LESSON 2/TASK 1
Since SGT Elliott received the proper responses, he will follow the yes
arrow to the next box of instructions. In the next box of instructions, he
is directed to place the TURRET POWER switch to the ON position. This time,
he is asked if the TURRET POWER indicator light (5) (figure 16 on page 82)
came on. In this instance, the light did not come on; therefore, he will
follow the no arrow to the next box of instructions.
In the next box of instructions, SGT Elliott is directed to place the TURRET
POWER switch and the MASTER POWER switch to the OFF position; then to
perform STE-M1/FVS test 2520. Test 2520 tests turret power distribution.
Before beginning this test, SGT Elliott first reads the Initial Setup
section of the test procedures. From this section, SGT Elliott finds that
he will need a turret mechanic's toolkit, STE-M1/FVS test set, and the a
45T10 (BFV turret mechanic) assistant. SGT Elliott will need three TMs as
references.
These TMs are: TM 9-2350-252-10-1, TM 9-2350-252-10-2, TM
9-4910-751-14-1. The vehicle should be stopped, with the engine off, turret
power shut down, and the weapons unloaded and safe.
Once the necessary tools, equipment, references, and personnel have been
gathered together and the vehicle has been configured according to the
Initial Setup section of the test procedure, SGT Elliott begins the test by
connecting the STE-M1/FVS test set to the vehicle distribution box and
performing the self-test. Since no faults were found with the test set, SGT
Elliott will follow the no arrow to the next box of instructions.
In the next box of instructions, SGT Elliott is directed to remove the
center and right turret floor plate. The procedure for removing these two
plates can be found on page 4-22 of TM 9-2350-252-20-2-2. Once the floor
plates have been removed, SGT Elliott enters test number 2520 on the SETCOM.
This time, SGT Elliott is asked if the SETCOM displays a cable instruction
message word number. Since the SETCOM does not display a cable instruction
message word number, SGT Elliott will follow the no arrow to the next box of
instructions. In the next box, SGT Elliott is asked if the SETCOM displays
a fault message. In this instance, a fault number (251805) is displayed
