M2/M3 BFV: TROUBLESHOOTING - OD1610 - LESSON 2/TASK 1
The first thing that SGT Elliott does is to read DA Form 2404.
After
reading DA Form 2404, SGT Elliott talks to the crew to get a little more
information; then he operates the vehicle in an attempt to duplicate the
malfunction. After ensuring that the malfunction exists as listed on the DA
Form 2404, SGT Elliott locates the troubleshooting procedure on page 3-81 of
the TM.
After he has found the troubleshooting procedure, SGT Elliott reads the
Initial Setup section to find out what necessary personnel and references
will be required and to find out the equipment conditions.
For this
malfunction SGT Elliott will need one helper (45T10, BFV Turret Mechanic),
and TMs 9-2350-252-10-1, 9-2350-252-10-2, and 9-2350-252-20-1.
The vehicle should be parked with the engine stopped, turret power shut
down, and the weapons unloaded and safe.
Once the necessary personnel and references have been gathered together and
the equipment configured according to the Initial Setup, SGT Elliott begins
his troubleshooting procedure. First, SGT Elliott places the MASTER POWER
(1) (figure 15) switch to the ON position.
The troubleshooting procedure
asks if the driver's instrument panel MASTER POWER INDICATOR light (2) comes
on, and does the driver's instrument panel voltmeter (3) read in the mid-
scale. In this instance, the light is on and the gage reads in mid-scale.
