BATTERY
CHECKING SPECIFIC GRAVITY
1 Read hydrometer and thermal gauge indica-
tions
as eye level.
Read top level with scale.
CAUTION:
a. If it becomes necessary to start the engine with a booster battery and jumper cables, use a
12-volt booster battery
b. After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact
c. Never add distilled water through the hole used to check specific gravity.
2. Convert into specific gravity at 20°C (68°F)
Example
e When electrolyte temperature is 35°C (95°F)
and specific gravity of electolyte is 1230,
converted specific gravity
at 20°C (68°F) is
Check
- Hydrometer 1 240
When electrolyte temperature
is 0°C (32°F)
and specific gravity of electrolyte
is 1.210,
converted specific gravity
at 20°C (68°F) is
1.196.
