TM 9-2350-256-34-1
2-21. Electrical Components
a. General. The electrical components allocated for
replacement by direct and general support
maintenance personnel are the high voltage power
pack, bilge pump electrical system components and
the miscellaneous leads and wiring harnesses com-
prising the vehicle electrical installation. The circuit
number of each cable is shown on a metal band at-
tached to the junction of terminal end of each cable.
Refer to TM 9-2350-256-20 for a listing of the circuit
numbers assigned to the vehicle and for the vehicle
wiring diagram.
WARNING
Certain precautions must be observed
when removing electrical components.
Accidental contact of metal tools be-
tween battery or starter cables and the
frame of the vehicle causes a direct
short circuit resulting in arcing and in-
stant heating of the tool to red hot. This
can cause painful burns on the hands
and serious damage to tools, vehicle
components and batteries. Moreover,
the overloaded battery may explode,
spraying hot acid and sharp fragments
over the surrounding area. The correct
procedure when removing electrical
equipment, harnesses, leads or cables is
to first turn off the master switch and
then disconnect the battery ground
cables. Protect the ground cables from
accidental contact with the battery ter-
minals. When the work has been com-
pleted, connect the battery ground
cables last.
CAUTION
When removing harnesses, leads and
cables, check circuit number markers. If
any are missing, illegible or damaged to
the extent that they might come off, tag
cables with correct circuit numbers
(refer to applicable wiring or schematic
diagrams in this chapter or the vehicle
wiring diagram in TM 9-2350-256-20)
prior to disconnecting them.
