echanics, before you hook up the
STE-M1/FVS to the Bradley, make
sure the J1, J2, J3 and J4 connectors
under the center floor plate are clean.
Dirt and dust inside these connec-
tors can give you false readings which
can lead to unnecessary repair and re-
placement costs.
Before you hook up the STE-M1/
FVS, blow out loose dirt and dust
from the connectors with compressed
air. NSN 6850-01-368-4797 gets a 10-
oz can of air. Order it on a DD Form
1348-6 from RIC GSA and put “NSN
not on AMDF” in the Remarks block.
Dust particles blown by com-
pressed air can be dangerous. Direct
the air stream away from your face
and others. Always wear safety glasses
to protect your eyes.

If the receptacles are really dirty or
covered with corrosion from moisture,
clean the pins with isopropyl alcohol,
NSN 6810-00-753-4993, and foam
swabs, NSN 7045-01-154-1317. Order
the swabs on a DD Form 1348-6 from
RIC S9E and put “NSN not on AMDF”
in the Remarks block.

Make a note of the new cleaning
procedure until it can be added to the
-20-2-1 TMs.
Once you’ve finished troubleshoot-
ing, make sure you put the dust caps
back on the connectors. They keep dust

reventing damage to your peri-
scope, NSN 6650-01-317-9138, is
easy, drivers. Just make sure you
store and use it properly.
Too many periscopes are dam-
aged when they’re left unstrapped
in the driver’s sponson stowage
bracket. As the vehicle moves, the
periscope bounces around in its
bracket—or on the floor.
Prevent that damage by strapping
the periscope in the driver’s spon-
son stowage bracket when it’s not
in use.
and make troubleshooting easier next time.
If the caps are missing, replace ’em. A
new J1 cap comes with NSN 5340-01-
147-0720. Get a new cap for the J2, J3
or J4 connector with NSN 5935-01-108-
9518.
Replace missing dust caps
Then, when you do use the peri-
scope, make sure the wingnuts that
hold it in place stay nice and tight.
That stops unnecessary bounces
while the periscope is in operation.
