T
he batteries on the diesel engine generator set (DEGS) on your AN/TSC-154
secure mobile anti-jam reliable tactical terminal (SMART-T) can get you in trouble
if you try to jump start the engine.
Soldiers have been seen using jumper cables in an effort to bring dead DEGS bat-
teries to life.
If the batteries are discharged or the battery charger has failed, you must replace
the batteries, NSN 6140-01-484-5341. Do not try to slave them or jump them.
If you're in a bind and need your SMART-T up and running, it can take DC power
from the HMMWV it's mounted on. You can also get AC power from another gen-
erator with the equivalent output of the PU-815 DEGS.
During the scheduled retrofit, warning stencils will be applied on the DEGS that
warn the user not to jumpstart or slave the batteries. Future additions to TM 11-
6115-481-13 will also have the warning.
A Ground Precautionary Message (CECOM GPM 03-006) was issued that pro-
vides additional details. SMART-T DEGS users should obtain copies of the message
and keep them with their TMs. Copies of the message can be obtained through your
local CECOM LAR or online at

T
he circuit card assemblies (CCAs) in
your frequency hopping multiplexer
(FHMX) are depot repairable items.
Stop throwing them away!
The CCAs are:
NSN 5998-01-424-2269, PN A3251884;
NSN 5998-01-422-6520, PN A3251869;

If you’re saying “Hold on a second, I
know that last one, NSN 5998-01-422-
9779, is a throwaway,” you need to get
updated. It once was, but now it’s not!
All these cards are now under a
depot repair program run out of

replacement to:
Tobyhanna Army Depot

And when you send in the cards, send
in all the parts, too! That includes cable
assemblies.
