rewmen, the rubber boots that cover the positive and negative terminals on your mobile
gun system (MGS) Stryker’s auxiliary battery box play an important role. If they’re missing
or damaged, an electrical short could happen. That short can cause a vehicle fire!
C
rewmen, the microclimate conditioning system (MCS) on your M109A6 Paladin
provides a safe environment inside your vehicle when operating under NBC
conditions.
But the MCS needs regular attention so it’ll work when you need it most.
In addition to the weekly
visual checks called for in the
-10 TM, be sure to operate the
MCS once a month. That’ll keep
the refrigerant loop from being
damaged and causing leaks.
Also, high-pressure water at
the wash rack gets forced inside
the MCS and is trapped there.
That’s bad news for the circuit
boards and other components.
Corrosion follows and that can
be expensive to repair.
It’s easy for you to prevent
corrosion. After running your
vehicle through the wash rack,
open the two drain cocks on the
cab’s ceiling just under the MCS.
Be sure to use a bucket to catch
the water so it doesn’t mess up
the turret.
The
rubber
boots
can
get
damaged or slide down the battery
cables, exposing the terminals.
Investigators
believe
missing
or
improperly
installed
battery
terminal boots caused a recent fire
that destroyed an MGS Stryker.
The rubber boots prevent metal
objects—like dropped tools and
other
items—from
coming
into
contact with the terminals and
causing electrical shorts and arcing.
During
AFTER
and
WEEKLY
PMCS, make sure the boots are
installed correctly and are in good
condition. If you find any that are
missing or damaged, your vehicle
is NMC until they’re replaced. The
negative terminal boot comes with
NSN
Get
the
positive terminal boot with 5930-
01-590-9078.
Also,
the
battery
box cover should be in place and
fastened tight.
Don’t forget to inspect the auxiliary batteries for cleanliness and signs of arcing such as
burned areas or melted spots on the rubber covers or metal parts. If you find problems,
report them.
