Components of the Hull Power Distribution System
There are seven components that comprise the hull power distribution
system.
These seven components will be discussed in the paragraphs
that follow.
a.
Batteries.
The vehicle electrical system uses four wet cell
batteries, wired in series/parallel, to supply electrical power when
the engine is not running. The batteries provide a normal operating
voltage of 27.5 volts with an amperage capability of 200 amps per
hour.
b.
DC Generator.
The do generator is used to recharge the
batteries and to supply electrical power when the engine is running.
Like the batteries, the generator is capable of producing 200 amps
per hour. The do generator is driven by the engine. The generator
charges the batteries in the vehicle and the turret when the engine
is running.
A regulator mounted on the generator keeps the voltage
at the correct level.
c.
Vehicle Power Distribution Box.
The vehicle power distribution
box is the main regulator for the vehicle electrical system.
The
electrical power flows from the batteries or the generator to the
vehicle power distribution box. The distribution box distributes the
power to the various accessories where needed.
The vehicle power
distribution box is located in the driver's compartment, to the left
of the driver.
d.
Battery Jumper/Conductor Bus.
The battery jumper/conductor bus
is a piece of heavy metal that is an excellent conductor of
electricity. In this
