M2/M3 BFV: HULL POWER DIST SYSTEM - OD1606 - LESSON 2/TASK 2
Item 7 of the troubleshooting procedure asks SGT Haskell the
question, DOES MULTIMETER READ 17 OR MORE VOLTS?
SGT Haskell looks
at the scale on the multimeter and observes that the voltage reading
is 22 volts.
After SGT Haskell makes the determination that
the voltage
measurement is greater than 17 volts, he then places the MASTER POWER
switch to the OFF position and reconnects plug 1W4P1 to jack 2AJ2.
Once the plug has been reconnected, SGT Haskell manually traverses
the turret to 6400 ails and then reinstalls the TURRET STEP FLOOR
PLATE following the procedures on page 4-3 of TM 9-2350-252-20-2-1.
SGT Haskell has completed the troubleshooting procedures for this
particular malfunction.
All that remains to be done is for his to
gather up tools and test equipment that were brought out to the
vehicle and to write up DA Form 2404 stating that the turret BACK UP
PWR indicator light is defective and needs to be replaced.
c.
Pathway Two.
In troubleshooting pathway two, we will
troubleshoot the hull power distribution system to an end result of a
faulty vehicle distribution box.
NOTE
The procedure described below is being used as an
example.
The test results described in this
pathway are not the only results possible when
performing
the
troubleshooting
procedures.
Always follow the directions in the TM for the
actual test results obtained when troubleshooting
on the vehicle.
After completing the troubleshooting procedures for the faulty turret
BACK UP PWR indicator light, SGT Haskell is assigned, by the motor
sergeant, to troubleshoot another BFV for a possible defective
vehicle power distribution box.
SGT Haskell once again gathers the necessary tools and equipment, and
ensures that the vehicle has been set up according to the INITIAL
SETUP procedures.
Once the INITIAL SETUP procedures are done, he
places the MASTER POWER switch to the ON position and checks the
volts gage for a reading.
