SERVICE
INFORMATION
GENERAL
A
kVARNMG
•
The
battery gives off explosive gases;
keep
sparks,
flames
and
cigarettes
away. Provide adequate
ventilation
when
charging.
•
The
battery
contains
sulfuric
acid
(
electrolyte
).
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
IS minutes
and
call
a
physician.
•
Electrolyte
is
poisonous.
—
If swallowed, drink large quantkiei
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 ignition
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
a
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

be
damaged
if
overcharged
or
undercharged,
or
if
left
to
discharge
for
a
long
period.
These
same
con-
ditions
contribute
to

'
of the battery
Evan
under normal
use,
the
performance
of
the battery
deteriorates
under
2-3
yea's
•
Battery voltage
may
recover
after
battery charging, but
under heavy
load, battery
voltage
will
drop
quickly
and
even-
tually
die out.
For
this
reason, the
charging
system
is
often
suspected
to
be
the
problem.
Battery
overcharge
often
results
from problems
in
the battery
itsolf.
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
bat-
tery
is
frequently
under heavy
load,
such as having
the
headlight
and
taillight
ON
for
long periods
of
time without
rid-
ing
the motorcycle.
•
The
battery
will
self-discharge
when
the
motorcycle
is
not
in
use.
For
this
reason,
charge
the battery
every
two weeks
to
provont
sulfation
from
forming.
•
Filling
a
new
battery with
electrolyte
will
produce
some
voltage, but
in
order
to
achieve
its
maximum
performance,
always chargo
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
