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.

STE-M1/FVS VTM.

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

discussed.

(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).

NOTE

Make sure that the VTM does not touch metal.

False readings can result when the VTM touches

metal.

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

vehicle, pull VTM circuit breaker (4) to the OFF position.

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

MANUAL position.

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

1A1J14.
