A
brief

of
the
principal
parts
of
the
electrical
sys-

is
presented
here
.
Also
covered

are
basic

.
Voltage
and
Polarity
The
vehicle
electrical
system
is
a
12-volt
direct
current
(DC)
negative-ground
system
.
A
voltage
regulator
controls
system
voltage
at
approximately
the
12-volt
rating
of
the
battery
.
Al¡
circuits
are
grounded
by
direct
or
indirect
