The battery gives off explosive gases; keep sparks, flames, andcigarettes away. Provide adequate ventilation when
charging or using the battery in
an
endosed space.
The battery contains sulfuric acid (electrolyte). Contact with skin or eyes may cause severe burns. Wear protective
clothinq and a face .shield.
- If electrolyte gets en your skin, flush with water.
- lf electrolyte gets in your eyes, flush with water for at least 15 minutes and call a physician immediately.
Electrolvte is poisonous. lf swall6wed, drink large quantities of water or milk and follow with milk of magnesia or vegetable
oil and calla physician. KEEP OUT OF REACH OF CHILDREN.
Always turn off the ignition switch 'betore disconnecting any electrical componente
CAUTION
Some electricalcomponents

be damaged if terminals or connectors are connectedor disconnected while the igni-
tion switchis ON and current is presento

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 sto red battery everytwo weeks.
For a battery remaining in a stored rnotorcvcle. disconnect the negative battery cable from the battery terminal.
NOTE
.
The maintenance free battery must be replaced when it reaches the end of itsservicelife.
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,
OT
of leftto discharge for long periods. These same condi-
tions contribute to shorteningthe "Iife span" of the battery. Even under normal use, the performanceof the battery dete-
riorates after 2-3 years.
Battery voltage may recover after battery charging, but under heavyload, battery voltage will drop qf¡ickly and eventuallv
die out. For this reason, the charging system is often suspected to be the problem. Battery overcharge often results from
problems in the hattery itself, which may appear to be an overcharge symptom. If one of the battery cells is shorted and
battery voltage does not lncrease. the requlator/rectifier supplies excess voltage to the battery. Under these conditions,
the electrolyte level goes down quickly. .
.
Before troubleshoóting the charging system, check for proper useand maintenance of the battery. Check if the battery
is frequently under heavy load, such as having the headright and taillight ON for long periods of time without riding the
motorcycle.
The battery will self-discharge when the motorcycle is notis use. For this reason, 'charqe the battery every two weeks
to prevent sulfation from forming.
Filling a new battery with electrolvte will produce some voltage, butin order to .achieve ItS maximum performance, always
chargethe battery. Also, the battery life islengthened whenit isinitial-charged.
When checking the charging
svstern,
alwaysfollow the steps in the.troubleshooting flow chart (page 13-3).
For battery testing/charging, refer to sectiori 22 of the Common Service Manual.
For charging system component locations. see page 13-2.
