ELECTRICAL SYSTEM
Your
boat
is
equipped
with
two
elecuical
systems; a
battery
powered
direct
current
(DC) system,
and
a
generator
or
shore
powered
alternat-
ing
current
(AC) system.
Each
system
has
a
master
panel.
The
DC
system
supplies
elecuicity
to
all
of
the
boat's
elecuical
circuits
(lights,
pumps,
blowers,
ignition,
etc.).
The
AC
system
supplies
power
to
the
port
and
starboard
electtical
out-
lets,
and
to
120 volt systems
(elecuic
stove,
water
heater,
microwave,
refrigerator
and
battery
charger)
when
the
boat
is
moored
at
the
dock.

Your
boat
has a 12 volt
negative
ground
DC
system.
The
positive wire
is
hot,
and
feeds
current
from
the
batteries
to
the
various
12
volt
systems,
and
the
negative
wire
is
the
ground
.
Your
boat
is
equipped
with
three
batteries
. Two
batteries
(cranking
bat-
teries)
are
used
only
to
start
the
engines.
Th
e
third
battery
is
an
auxiliary
battery
which
prmides
power
to
all
of
the
other
DC
elecuical
circuits via
the
master
banery
switch.
When
the
engines
are
running,
all
batteries
are
charged
by
the
two
engine
alternators
and
the
rate
of
charge
is
controlled
by
voltage
regula-
tors.
The
electrical
sys
t
em
is
grounded
by
grounding
th
e
cranking
batteries
to
the
engines,
and
the
auxiliary
battery
to
the
cranking
batteries.
The
engines
are
connected
by
ground
cab
le to
pro\ide
added
assurance
that
a
good
ground
is
being
achieved.
The
engines
are
then
grounded
to
a
bonding
suip
located
in
the
engine
compartmenL
The
auxiliary
battery
is
separated
[rom
the
cranking
batteries
by
an
elec-
tronic
solid
state
isoiaLOf.
\Vhen
the
engines
and
ignition
switches
are
"ofr.
the
i
solator
prevents
accessory
loads from
depleting
the
cranking
batteries
.
When
the
batteries
are
being
charged
b)'
the
alternato
rs,
the
isolator
automatically
combines
and
isolates
the
alte
rnator
output
and
disuibutes
the
charge
among
the
batteries
according
to
individual
need.
DC MASTER PANEL
The
DC
master
panel
consists
of
a voltmeter, a series
of
switch type
and
reseuab
le
circuit
breakers,
and
the
master
breaker
switch.
