Specific
Gravity
1.
Check the specific gravity
of
the electrolyte
in
each cell with a
hydrometer.
2.
When the electrolyte temperature differs from that at which the
hydrometer was
calibrated, correct the specific gravity reading
following the formula mentioned
in
(Reference).
3.
If the specific gravity is less than 1.215 (after it
is
corrected for
temperature), charge or replace the battery.
4.
If the specific gravity differs between any two cells by more than
0.05, replace the battery.
• NOTE
•
Hold
the
hydrometer
tube
vertical
without
removing
it
from
the
electrolyte.
•
Do
not
suck
too
much
electrolyte
into
the
tube.
•
Allow
the
float
to
move
freely
and
hold
the
hydrometer
at
eye
level.
• The
hydrometer
reading
must
be
taken
at
the
highest
electrolyte
level.
(Reference)
• Specific gravity slightly varies with temperature. To be exact, the
specific gravity decreases by 0.0007 with an increase
of
1 °C
3EEABAB1P035B
(0.0004 with
an
increase
of
1°F)
in temperature, and increases
by 0.0007 with a decreases
of
1 °C (0.0004 with a decrease
of
1
OF).
Therefore, using
20°C
(68
OF)
as a reference, the specific gravity
reading must be corrected by the following formula:
- Specific gravity at
20°C
= Measured value + 0.0007 x
(electrolyte temperature - 20
0c)
- Specific gravity at 68
of
= Measured value + 0.0004 x
(electrolyte temperature 68
OF)

1.
Remove the under cover panel.
2.
Disconnect the 4P connector (4) and remove the main switch (1).
3.
Measure the voltage with a voltmeter across the connector 30
(red) terminal and chassis.
4.
If the voltage differs from the battery voltage
(11
to 14 V), the
wiring harness is faulty.
