Service Information
A
WARNING
The
battery gives
off
explosive gases;
keep
sparks, flames,
and
cigarettes
away.
Provide
adequate
ventilation
when
charging
or
using the battery
in
an enclosed space.
The
battery contains
sulfuric
acid
(eiectrolyte).
Contact
with
skin or
eyes
may
cause severe
burns.
Wear
protective
clothing
and
a face
shield.
—
If
electrolyte
gets
on
your
skin,
flush
with water.
—
If
electrolyte
gets
in
your
eyes,
flush
with
water
for at least
IB minutes and
call
a physician immediately.
Electrolyte
is
poisonous.
If
swallowed,
drink large quantities of
water
or milk
and
follow with milk
of
magnesia
or
vegetable
oil
and
call
a physician.
KEEP
OUT
OF REACH OF
CHILDREN.
Always
turn
off
the
ignition
switch
before disconnecting
any
electrical
component.
CAUTION
Some
electrical
components
may
be
damaged
if
terminals
or
connectors
are
connected
or
disconnected
while the
igni-
tion
switch
is
ON
and
current
is
present.
••
•
For
extended
storage,
remove
the
battery,
give
it
a
full
charge,
and
Store
it
in a
cool,
dry
space.
For
maximum
service
life,
charge
the stored battery every .two
weeks.
'
•
For
s
battery
remaining
in
a
stored
motorcycle, disconnect the
"negative battery cable
from
the battery
terminal.
NOTE
•
The maintenance
free
battery
must
be replaced
when
it
reaches
the
end
of
its
service
life.
CAUTION
*
The
battery
caps should
not be
removed. Attempting
to
remove
the
sealing
caps from
the
cells
may
damage
the
battery.
The
battery
can be
damaged
if
over charged
or
undercharged,
or of
left
to
discharge
for
long periods.
These same
condi-
tions
contribute
to
shortening the
"life
span''
of
the
battery.
Even under normal
use, the
performance
of
the
battery dete-
riorates after
2-3
years.
•
Battery voltage
may
recover
after
battery charging,
but
under heavy
load,
battery voltage
will
drop
rjfjickly
and
eventually
die out.
For
this
reason, the charging
system
is
often
suspected
to
be the
problem.
Battery
overcharge
often
results
from
problems
in
the battery
itself,
which
may
appear
to
be
an overcharge
symptom.
If
one
of
the battery
cells
is
shorted
and
battery voltage
does
not increase, the
regulator/rectifier
supplies
excess
voltage
to
the
battery.
Under
these
conditions,
the
electrolyte
level
goes
down
quickly.
-
Before troubleshooting the charging
system, check
for
proper use
and maintenance
of
the
battery.
Check
if
the battery
is
frequently
under
heavy
load,
such as having
the headlight
and
tailiight
ON
for
long periods
of
time without
riding
the
motorcycle.
•
The
battery
will
self-discharge
when
the
motorcycle
is
not
is
use. For
this
reason,
charge
the battery
every
two weeks
lo.
prevent
sulfation
from
forming.
•
Filling
a
new
battery'with' electrolyte
will
produce
some
voltage, but
in.
order
to
achieve
its
maximum
performance,
always
charge
the
battery. Also,
the'
battery
life
is
lengthened
when
it
is
initial-charged.
•
When
checking
the charging
system,
always
follow The steps
in
the.
troubleshooting flow chart (page
13-3).
•
For battery testing/charging,
refer
to
section
22
of
the
Common
