oes your unit have an M915A4 truck that won’t start and has no light on the shift
tower? Or does the shift selector in your
M915A4 truck’s cab no longer shift into
drive? In both cases, the problem may be
a missing fuse.
The factory mislabeled some of the
M915A4’s fuses as spares. They’re not
really spares because each one is needed
for your truck to run right.
The solution is to keep
all
fuses installed
in the fuse panel. Be sure there’s a fuse in
every empty slot. Then keep extra fuses in
your glove compartment. You may need
them later.
Dear Editor,
TM 9-2320-387-24P for the expanded capacity utility truck shows the
wrong NSN in WP 0151 01-1 for the open-end wrench. The correct NSN is
I think it’s important mechanics make a note of the correct NSN because
the wrench doubles as the handle for the spare tire assembly on the Expanded
Capacity Vehicles (ECV) HMMWVs. And it often disappears in the field.

Editor’s note:
This will eventually be corrected in the
TM, but until it is mechanics should pencil in the right
NSN. Thanks for letting us know, Sergeant.

rivers, the
last
thing you want in a tactical situation
is the backup alarm going off on your M-ATV.
So, make sure it
won’t.
Just use the switch on the
dash to shut off the alarm.
When you’re backing up your vehicle without the
backup alarm, use a ground guide and lots of extra
caution when the tactical situation allows.
