SECTION III: PRINCIPLES OF OPERATION
e. MISCELLANEOUS ELECTRICAL COMPONENTS
Riggers light selector switch. The riggers light selector switch contains a three-position toggle switch that
controls the operation of the riggers service and IR light.
Accessories panel. The accessories panel contains the accessory outlet socket, a two-position winch light
toggle switch, a two-position ventilating blower toggle switch, a two-position bilge pump toggle switch, a
two-position generator toggle switch, a bilge pump lamp, and a generator lamp.
Ventilating blower. An electric motor driven ventilating blower draws fresh air from outside the vehical into
the crew compartment for ventilation.
f. CONDUITS, CABLES, AND CONNECTORS
Conduits. Flexible, metallic conduits are used on high-voltage cables to prevent electrical radiation which
might interfere with communications equipment.
Cables. Electrical cables are rubber covered. The ends of all cables terminate in a pin or socket on a
connector, plug, or receptacle, or at a cable terminal. The cables are crimped or soldered to the pins sockets,
terminals, or ferrules.
Plug and receptacle-type connectors. The plug has four main components: the shell assembly coupling nut.
grommet, and retaining nut. The receptacle has three components: the receptacle assembly grommets and
retaining nut. The receptacle is secured to a box or panel with four screw. The plug is secured to the
receptacle with the coupling nut. A waterproof connection is made with the retaining nut by compressing the
grommet to the ends of the plug or shell assemblies. The shell and receptacle assemblies have either pins or
sockets for one or many electrical connections.
4 Waterproof rubber connectors.
Each connector has a male and female component. The female portion
consists of a rubber shell, sleeve, and ferrule. The male part consists of a rubber shell, C-washer, and
terminal. The friction-fit union of the two halves forms a waterproof connection.

The following callouts are found in Figure 1-10.
The cross-drive transmission (3) is a combined transmission with steering unit and two output reduction drives (1
and 2). It transmits power directly from the engine to the track drive sprockets. The transmission is controlled by
the vehicle operator by means of the shifting and steering controls and linkages, and the brake control peda1
The cross-drive transmission (3) includes a hydraulic torque converter, a split torque drive. variable steering, and
disk-type brakes. The transmission delivers engine power to the track sprockets at an output torque which varies
automatically according to the driven-load conditions when not in linkup.
There are three forward speed ranges and one reverse
Steering is possible in all drive ranges and N (neutral). Steering in N (neutral) causes the vehical to pivot in place,
with the tracks turning in opposite directions.
