f you’re in the front seat of a ve-
hicle with the AN/VRC-97 mobile
subscriber equipment receiver-trans-
mitter (MSRT), you can’t see the af-
filiation indicating light. It’s mounted
on the RT in the back of the vehicle.
If you can’t see the light, you can’t
tell if you’re affiliated. If you’re not
affiliated, you can’t receive calls.
Now you can get a remote affiliat-
ion indicator that solves the problem.
It mounts in the front of the vehicles
on the MSRT remote power switch
box in all vehicles except the M1065
and M1067 SUSVs and the M1025. On
these vehicles it is mounted where it
can easily be seen, according to direc-
tions in the TB. When the affiliation in-
dicating light on your RT in the back of
the vehicle lights up, the one on the re-
mote indicator lights up, too.
There are three remote affiliation in-
dicator kits available:
ID-2533(V)1, NSN 6220-01-421-
4394, is used on the M1008 and M1009
CUCVs, and M998 two- and four-door
and M1025 HMMWVs.
ID-2533(V)2, NSN 6220-01-421-
4412, is used on the M1065 SUSV.
ID-2533(V)3, NSN 6220-01-421-
4413, is used on the M1067 SUSV.
The kits are covered in TB 11-5800-
216-13-8. For technical information on
the kits, write, call or e-mail CECOM at:

Look at the lights. Are any broken?
Do they all work?
If you have air brakes, the air tanks
should have been drained after the last
operation. If they weren’t, you might
have frozen or corroded lines.
Check the petcock. After your air
tanks were drained, the petcock should
have been closed. Many aren’t, though,
and an open petcock lets condensation
form in the tank.
Don’t forget the emergency hand
brake. Check it. Never set it if your
trailer is being stored for a long time
or if you’re expecting freezing weather.
The cable and handle can freeze and
break when you try to use them. Then
you can’t release the brake. Use chocks
when you can’t use the handbrake.
Finally, check the brakes. If you have
hydraulic brakes, check the master cyl-
inder to make sure there’s enough fluid
Don’t forget about the grounding
bolt. Vibration loosens this bolt and
water corrodes the ground connection.
Coat the bolt and terminal with RTV
sealant, NSN 8040-00-118-2695. RTV
seals out moisture and helps keep the
bolt tight.
Your walk-around should include a
hand check of all bolts for tightness.
Eyeball them for corrosion, too. If the
corrosion hasn’t got a foothold yet,
brush it away with a stiff-bristled brush.
Corrosion that has pitted the bolt,
means the bolt needs to be replaced.
All bolts tight?
Corroded?
Grounding bolt in good shape?
All lights working?
in it. If there is not enough, check for
leaks.
Check that brake!
