SERVICE INFORMATION
GENERAL
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 water or milk and call your local Poison Control Center or a physician immediately.
• Always turn "OFF" the ignition switch before disconnecting any electrical component.
• Some electrical components may be damaged if terminals or connectors are connected or disconnected by 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.
•
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 not increase, the regulator/rectifier supplies excess voltage to the battery. Under these conditions, the electrolyte level
goes down quickly.
The battery will self-discharge when the motorcycle is not in use. For this reason, charge the battery every two weeks to prevent
•
salvation from occurring.
When checking the charging system, always follow the steps in the troubleshooting flow chart (page 15-2).
•
Refer to the alternator removal and disassembly (page 10-16).
•
BATTERY TESTING
Refer to instructions in the Operation Manual (page 15-3) for the recommended battery tester 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: FBT-50
