impractical to attempt to describe all the troubleshooting pathways.
Therefore, this subcourse will deal with only a few of the major
pathways that comprise this troubleshooting task.
Since the objective of this portion of the subcourse is to illustrate
on the M2/M3 BFV, the procedures for replacing faulty components will
not be covered here. The procedures for replacing faulty components
were previously covered in paragraph 4 on page 5 in lesson 1.
When following the troubleshooting pathways in this subcourse, it is
important to remember that the test results described are not the
only possible results. The pathways are being used as examples only.
Throughout the troubleshooting pathways, we are going to use a

It is essential to have the technical manual (TM)
present and to respond to the specific test results obtained
according to the directions in the TM if actual troubleshooting
procedures are to be performed on the vehicle. Also, this subcourse
assumes that whenever a test is performed, the test equipment or
multimeter has been properly set up for the test being described.
Before beginning a troubleshooting
task, it is important to have on hand the tools and parts required
and to make sure the vehicle is properly set up for the task at hand.
For this troubleshooting task, the vehicle engine should be stopped,
the FIRE SUPPRESSION switch should be in the MANUAL position, the
ramp should be down and the turret should be shut down. The general
mechanic's tool kit, multimeter, electrical connector pliers, probe
assembly, and the STE-M1/FVS vehicle test meter (VTM only) will be
needed for this task.
When actually performing the step-by-step
procedures on the vehicle, a helper may be needed, depending on the
test results obtained.
