pecial equipment mounted in or on your HMMWV—like a rear-mounted radio,
a commo shelter, an ambulance body or an arctic personnel shelter—often draws
electricity directly from the truck's batteries.
That means turning off the master switch on the dashboard does
not
turn off the
battery power to the equipment in back.
So make sure
all
electrical switches in the
vehicle are off before you leave the truck. If
you don't know where all of them are located,
get a medic or specialist to show you what to
look for.
If a switch is left on, power will continue to
drain from the batteries. You could be left with
no power to start your truck.
One battery drain often forgotten is the
white lights in the ambulance. Its switch has
three positions and only one ensures that no
lights come on when the doors are opened or
closed. It's marked
OFF.

If you leave the speed switches set to HI
and the selector switch set to REMOTE
CONTROL, battery power continues to
go to the remote control panel. That can
kill your vehicle's batteries.
Until the TM is updated, note this
information and save some battery money
and slaving time.
SELECTOR switch on the fixed con-
trol panel must also be set to
WRECKER CONTROL PANEL. TM
9-2320-366-10-2 fails to mention
either setting.
hen you've finished winching
operations with your M1089 wrecker,
make sure the batteries don't run down
before your next mission.
Both main winch speed switches on
the remote control panel must be set to
