BATTERY
CHARGING
CIRCUIT
The
DC
Circuit
on
the
BCG ·functions
to
start, operate
and
st.op
the generator's engine. The circuit
is
best
understood
by
reviewing
the
DC
Wrring
Diagram
and
Wrring
Schematic.
The engine's
DC
wiring
is
designed
with
three simple
basic
circuits:
start,
run
and
stop.
The
engine
has
a
12
volt DC electrical control circuit that
is
shown
on
the
Wrring
Diagrams. Refer
to
these
diagrams
when
troubleshooting or
when
servicing
the
DC
electrical
system
or
the
engine.

Specifications
The
minimum
recommended capacity
.of
the battery used
in
the engine's 12-volt DC control circuit
is
400
CCA.
BATTERY
CHARGER
The generator supplies a continuous 10
amp
charge
from
its
battery charger
to
the starting battery.
To
test the battery
charger put a multimeter between the positive ( +) and
negative(-)
leads to the battery. It should indicate
13.5V
.to
14V
with
the
engine running.
If
only

indicated, check that the battery charger terminal connections
are
tight.
With
the unit running, test between the ( +)
and
(-)
tenninals
fod3.5V
to
14V.
If
no
charge
is
i9dicated, replace
the
charger.

Battery
Maintenance
Review
the
manufacturer's recommendations
and
then
estab-
lish
a
systematic
maintenance
schedule for your engine's
starting
batteries
and
house
batteries.
•
Monitor
your
voltmeter
for
proper charging
during
engine
operation.
•
Check
the
electrolyte
level
and
specific gravity
with
a
hydrometer
.
•
Use
only
distilled
water
to
bring
electrolytes
to
a
proper
level.
•
Make
certain
that
battery
cable
connections
are
clean
and
tight
to
the
battery
posts
(and
to
your engine).
•
Keep
your batteries
clean
and
free
of corrosion.
A
WARNING:
Sulfuric
acid
in
lead
batteries
can
cause
severe
bums
on
skin
and
damage
clothing.
Wear
protective
gear.
