NOTE
•
Hold
the
hydrometer
tube
vertical
without
removing
it
from
the
electrolyte.
•
Allow
the
float
to
move
freely
and hold
the
hydrometer
at
eye level.
• The hydrometer reading
must
be taken
at
the

A CAUTION
• Never remove
the
battery
cap
while
the
engine is running.
• Keep electrolyte
away
from
eyes. hands and clothes.
If
you
are spattered
with
it,
flush
with
water
immediately. and
see
your
doctor.
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)
below.
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.
(Reference)
• Specific
gravity
varies
slightly
with
temperature. To be exact,
the
specific
gravity
decreases
by
0.0007 (0.0004)
with
an
increase
of
1
°C
(34
OF)
in
temperature,
and increases
by
0.0007
(0.0004)
with
a decrease
of
1
°C
(34
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
ac
= Measured value + 0.0007 x
(Electrolyte
temperature
- 20°C)
Specific gravity
at
68
OF
= Measured value + 0.0004 x
(Electrolyte
temperature
- 68

Terminal Voltage
1.
Disconnect
the
4P
connector
from
the
main switch.
2. Measure
the
voltage
with
a
voltmeter
across
the
terminal
(1)
and
chassis.
3.
If
the
voltage
differs
from
the
battery
voltage,
the
wiring
harness
is
faulty.
