Service Information
General Safety
● The maintenance-free (MF) battery does not require battery acid level inspection. Do not replenish distilled
water.
● To charge the battery, remove the battery from the frame, and charge it with its seal-cap closed.
● Unless required in an emergency, do not carry out battery quick-charging.
● Always charge battery based on the current and time specified on top of the battery.
● Use a tester to check the charging status (open voltage).
● Do not replace the battery with a general-type battery.
● Check the charging system in sequence based on troubleshooting table.
● Test-charging systems while they are mounted on the motorcycle.
● For information on generator disassembly, refer to section 8.
