BATTERY CHARGING

WARNING

Corrosion hazard.

Batteries contain acid. Always keep the battery upright and do not spill the electrolyte. Avoid contact with skin and eyes.

Explosion hazard.

Changing the battery produces explosive hydrogen gas. Only charge the battery in a well ventilated area, away from any ignition source such as a water heater, electric motor, or a lit cigarette.

Wear Protective Equipment

Always wear gloves and safety glasses when handling the battery and battery cables.

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, contact your local 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 temperature is at least 60° F). Do not charge at a rate higher than 10 amps.
