M2/M3 BFV: HULL POWER DIST SYSTEM - OD1606 - LESSON 2/TASK 1
In the paragraphs that follow, we will discuss the TS-352B/U
multimeter and the simplified test equipment-M1/fighting vehicle
system (STE-M1/FVS) vehicle test meter (VTM only) will be discussed.
The VTM is the only component of the STE-M1/FVS test set that will be
used to troubleshoot electrical system malfunctions on the BFV.
In the paragraphs that follow, the procedures
for connecting the VTM to either diagnostic connector assembly 3 or
13, and for connecting the VTM to the vehicle batteries, will be
(1) Hook Up STE-M1/FVS (VTM only) to DCA 3 or 13. To hook up the
VTM to either of these diagnostic connector assemblies (DCAs), first,
remove the VTM (1) (figure 33 on the following page) and cable W1 (2)
from the transit case (3).
Make sure that the VTM does not touch metal.
False readings can result when the VTM touches
Once the VTM and cable W1 have been removed from the transit case,
move the equipment out to the vehicle. After the equipment is at the
Before the VTM can be connected to the vehicle, be sure that the
engine is stopped and that the FIRE SUPPRESSION switch is in the
Now connect plug W1P1 (5) (figure 34 on the
following page) to jack J1 (6) on the VTM.
When connecting plug
W1P1, care must be taken not to bend or break pins.
If plug W1P2 is being connected to 1A1J14, which is DCA 3, perform
the following procedures. First, remove the protective dust cap (3)
(figure 35 on page 44) on jack 1A1J14 (2). Now install plug W1P2 (1)
on jack 1A1J14. If plug W1P2 is being connected to jack 1A1J15 (DCA
13) (4), the procedures are the same.
The only difference is the
location of the jack. Jack 1A1J15 is to the immediate right of jack
