Battery Service
WARNING
Keep open flames and sparks away from the battery; the
gasses coming from it are highly explosive. Ventilate the
battery well during charging.
Checking Battery Voltage
A voltmeter can be used to determine condition of the battery.
When the engine is off, the voltmeter shows battery voltage,
which should be 12 volts. When the engine is running, 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. For example, it may
mean that the alternator is not charging the battery properly.
If there is any doubt about the cause of the problem, see
your authorized Snapper Pro® servicing dealer. If you need
to replace the battery, follow the steps under Cleaning the
Battery and Cables.
