BATTERY/CHARGING SYSTEM
SERVICE INFORMATION
GENERAL
AWARNING
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 15 minutes and call a physician immediately.
Electrolyte
is poisonous.
-
If
swallowed,
drink large quantities of waler or milk and caU your local Poison Control Center or a physician immediately.
Always tum OFF the ignition switch before disconnecting any electrical component.
Some electrical components may be damaged
if
terminals or connectors
are
connected
or
disconnected while the ignition switch
is ON and current is present.
This model comes with
a
maintenance free (MF) battery. The maintenance free battery must be replaced when it reaches
the
end of its service life.
For extended
storage,
remove
the
battery,
give it a full charge, and store it in a cool, dry space.
For a
battery remaining
in a stored motorcycle, disconnect the negative battery cable from
the
battery terminal.
The battery sealing caps should not be
removed.
Attempting to remove the sealing caps
from
the cells may damage the
battery.
The battery can be damaged if overcharged or undercharged, or if left to discharge
for
a long period. These same conditions
contribute to shortening
the
life span of the battery.
Even
under normal use, the performance of the
battery
deteriorates after
2-3 years.
Battery voltage may recover after battery charging, but under heavy
load,
battery voltage will drop quickly and
eventually
die out.
For this
reason,
the charging system is often suspected as
the
problem.
Battery
overcharge often results
from
problems in the
battery itself, which may appear to be an overcharging
symptom.
If one of the battery cells is shorted and battery voltage does
nol 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.
The battery will self-discharge when the
motorcycle
is not in use. For
this
reason, charge
the
battery every 2 weeks to prevent
sulfation from occurring.
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 initially charged
.
When checking the charging system
,
always
follow
the steps in the troubleshooting flow chart (page 16-5).
For altemator removal (page
11-5).
BATTERY
CHARGING
Tum power ON/OFF at the
charger,
nol at the battery terminal.
For
battery charging, do not exceed the charging current and
time
specified on the
battery.
Use
excessive
current or extending
the charging
time
may damage
the
battery.
Quick charging should only be done
in
an
emergency;
slow charging is
preferred.
BATTERY
TESTING
Refer
to the
instruction in the Operation Manual for
the
recommended
battery
lester for details
about
battery testing. The
recommended battery tester puts a "load" on the battery so that
the
actual battery condition can be measured.
Recommended battery tester
Micro 404XL
(U.S.A. only)
