CHECKING THE BATTERY
A voltmeter can be used to determine condition of bat-
tery. When engine is off, the voltmeter shows battery
voltage, which should be 12 volts. When engine is run-
ning, the voltmeter shows voltage of charging circuit
which normally is 13 to 14 volts.
A dead battery or one too weak to start the engine may
not mean the battery needs to be replaced. It may, as an
example, mean that the alternator is not charging the
battery properly. 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 Normal Care Section.
CHARGING A COMPLETELY
DISCHARGED
BAlTERY
Keep open flames and sparks away from the bat-
tery; the gasses coming from it are highly explo-
sive. Ventilate the battery well during charging.
1. Be aware of all the safety precautions you should
observe during the charging operation. If you are
unfamiliar with the use of a battery charger and
hydrometer, have the battery serviced by your dealer.
2. Add water sufficient to cover the plate (fill to the prop-
er level near the end of the charge). If the battery is
extremely cold, allow it to warm before adding water
because the water level will rise as it warms. Also, an
extremely cold battery will not accept a normal
charge until it becomes warm.
3. Always unplug or turn the charger off before attach-
ing or removing the clamphonnections.
4. Carefully attach the clamps to the battery in proper
polarity (usually red to [+] positive and black to
[-]
negative).
5. While charging, periodically measure the temperature
of the electrolyte. If the temperature exceeds
125”
F
(51.6” C), or if violent gassing or spewing of elec-
trolyte occurs, the charging rate must be reduced or
temporarily halted to prevent battery damage.
