M2/M3 BRADLEY FIGHTING VEHICLE: TURRET - OD1609 LESSON 3/TASK 2
(c)
If no faults are found in wiring harness 2W202 during tests 2390 and
2391, the problem could be a loose connection.
Therefore, the next step is to
check various connections for tightness.
(2)
Testing Connections for Tightness.
If the problem showing up in the
turret traverse is not being caused by a faulty wiring harness 2W202, move the
MASTER POWER switch to OFF.
Then turn the TURRET POWER switch to OFF and remove
the step turret floor plate and right turret floor plate (TM 9-2350-252-20-2-2,
page 4-22).
The following cable connections should be checked to isolate the
problem.
(a) Check the connection of cable 2W1P1 to 2A7J1 on the diagnostic panel
and cable 2W1P2 to 2A1J1 on the vehicle distribution box. If either connection is
loose, tighten it.
(b) Next, check the tightness of cable connection 2W301P4 to 2A1J4 on
the distribution box, and tighten if loose.
(c)
Manually traverse the turret to 3200 mils (TM 9-2350-252-10-2). Inspect
cable connection 2W301P1 to 2A200J1 (figure 28 on the following page). Tighten the
connection if needed.
(d)
Manually traverse the turret to 3700 mils (TM 9-2350-252-10-2). Inspect
and tighten, if necessary, the connection of 2W307P8 to 2A200J8 (figure 29 on the
following page).
(e)
Manually traverse the turret to 6400 mils (TM 9-2350-252-10-2).
Check
and tighten, if needed, the cable connection 2W307P2 to 2A201J2 (figure 30 on page
135).
(3)
Repeating Test 2650. When all connections are tight, manually traverse
the turret to 3200 mils (TM 9-2350-252-10-2). Install plug 2W202P1 to jack 2W200J4
and install the cap on the diagnostic panel jack J3, if earlier test procedure
steps (i.e., SETCOM messages, etc.) required their removal. Whenever a corrective
action has been taken in the test and inspection procedure, test 2650 should be
performed again to see if the symptom has been corrected. This should be continued
until a NO FAULTS FOUND condition exists.
