BATTERY CHARGING
A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other
electrical component. If there is any doubt about the
cause of the problem, see your dealer. If you need to
replace the battery, follow the steps under Cleaning the
Battery & Cables in the Regular Maintenance Section.
To charge the battery, follow the instructions provided by
the battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge
the battery until fully charged (until the specific gravity of
the electrolyte is 1.250 or higher and the electrolyte tem-
perature is at least 60° F). Do not charge at a rate high-
er than 10 amps.
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
