BATTERYCARE
Check battery cells with a hydrometer. The specific
gravity reading should be approximately 1.260 at
77°F (25OC).
If
one or more cells are low on water, add distilled
water and recharge. Keep the battery case clean and
dry. An accumulation of moisture will lead to a more
rapid discharge and battery failure.
Keep the battery terminals clean and tight. Push the
cable terminal down flush with or slightly below the
top of the battery post. After making connections,
coat the terminals with a light application of petro-
leum jelly or grease to retard corrosion.
Poor contact at the battery cable connections
is
oflen a source
of
trouble. Make sure battery cables are in good condition and that
contacting surfaces are clean and tightly connected.
Do
not
reverse battery leads. Use recommended battery tools when dis-
connecting leads to avoid mechanical battery damage.
WARNING
Ignition
of
explosive battery gases
i
might cause severe personal iniury.
Do
not smoke while servicing batteries.
BATTERY CHARGING, ALTERNATORS
The flywheel alternator is a permanent magnet alter-
nator and uses
asolid-state voltage
regulator-rectifier
for controlling output. Figures

Weak ignition spark or a discharged battery indicate
trouble
in
the charging system. But before testing the
charging system, always check the battery for service-
ability.
'
Keep these points in mind when testing
or
servicing
the flywheel alternator:
1.
Be sure output control plug (connector)
is
in-
serted properly. The plug must bottom in recept-
acle-eliminates any resistance due to a poor
connection. Keep clean and tight.
2.
Make sure alternator stator leads are not shorted
together.
3.
Be sure regulator-rectifier output control has a
good ground connection. Mating surface for
mounting must be clean and fasteners tightened
properly.
4.
Never reverse the battery leads.
Charging system tests require a
fully
charged battery.
