SERVICE INFORMATIONN

GENERAL INSTRUCTIONS

• The battery can be charged and discharged repeatedly. If a discharged battery is not used for a

long time, its service life will be shortened. Generally, the capacity of a battery will decrease after
it is used for 2_ 3 years. A capacity-decreased battery will resume its voltage after it is recharged
but its voltage decreases suddenly and then increases when a load is added.

• When a battery is overcharged, some symptoms can be found. If there is a short circuit inside the

battery, no voltage is produced on the battery terminals. If the rectifier won‘t operate, the
voltage will become too high and shorten the battery service life.

• If a battery is not used for a long time, it will discharge by itself and should be recharged every 3

months.

• A new battery filled with electrolyte will generate voltage within a certain time and it should be

recharged when the capacity is insufficient. Recharging a new battery will prolong its service life.

• Inspect the charging system according to the sequence specified in the Troubleshooting.

• Do not disconnect and soon reconnect the power of any electrical equipment because the electronic

parts in the regulator/rectifier will be damaged. Turn off the ignition switch before operation.

• It is not necessary to check the MF battery electrolyte or fill with distilled water.

• Check the load of the whole charging system.

• Do not quick charge the battery. Quick charging should only be done in an emergency.

• Remove the battery from the motorcycle for charging.

• When replacing the battery, do not use a traditional battery.

• When charging, check the voltage with an voltmeter.
