WESTERBEKE
recommends
that
the
following
generator
tests
and adjustments
be
peiformed
by
a qualified
technician.
DESCRIPTION
The
BC
generator
is
a brushless, self-excited generator
which
requires
only
the
driving
force
of the engine
to
produce
an
AC
output.
The stator houses two
sets
of
windings;
the
main
stator windings
and
the exciter
windings.
When
the
generator
is
started,
residual magnetism
in
the four rotating poles
induces a current in the stator which
then
generates
an
even
larger current
in
the exciter windings.
This
mutual
build
up
of
current
in
the
four
rotating
poles
and
in
the
exciter
windings
quickly
reaches
the
saturation point of the capacitor(s)
and
a
regulated
energy
field
is
then
maintained in the
stator.
At the
same
time,
this
regulated
field
produces a steady
voltage
in
the
stator
windings
which
can then
be
drawn off
the
genera-
tor's
AC
terminals
to
operate
AC
equipment.
The
generator is
a single-phase, reconncctable
120
volt
AC
two-wire or
120/240
voltAC
three-wire,
at
60

or

Wire
or
220

two-wire,
at
50
hertz.
Refer
to
the
SPECIFICATIONS
section of
this
manual
for
generator rat-
ings.
The
generator's data plate
gives
the
voltage,
current
and
frequency
rating of the generator.
An
AC
wiring
decal
is
affixed
to
the
inside of the louvered cover
at
the
generator
end.
A diagram of
the
various
AC
voltage
connections
is
pro-
vided
on
the
decal.
An
Integral Controller
(IC)
is
mounted
inside
the
generator
and
supplies a continuous
DC
charge
to
the
generators starting battery
when
the generator
is
running.

the

CHARGER section
in
this
manual.
Circuit
Breaker
A circuit breaker
is
installed
on
all
single phase
WESTERBEKE generators. This circuit breaker
will
auto-
matically disconnect generator power
in
case of
an
electrical
overload.
The
circuit breaker can be manually shut off
when
servicing
the
generator
to
ensure that
no
power
is
coming
into the
boat.
NOTE:
This
circuit
breaker
is
available
as
a
VVESTERBEKE
add-on
kit for earlier model
generators;
contact your
WESTERBEKE
dealer.
