NISSAN SERENA 1993 Service Repair Manual

POWER
SUPPLY ROUTING
Fuse
a. It fuse is blown,
be sure to eliminate cause of problem
before installing
new fuse.
b. Use fuse
of specified rating.
Never use fuse of more than
specified rating.
c. Do not install fuse in
oblique direction; always insert it into
luse holder properly.
d. Remove fuse lor clock if vehicle is not
used for
a lono
period of time.
Fusible Link
A melted
fusible link can be detected
by visual
inspection.
lf its
condition is questionable,
use circuit tester or
test lamp.
CAUTION:
a. ll lusible link should melt, it
is possible
that critical
circuit
(power supply or large
current carrying
circuit) is
shorted.
In such a case, carefully
check and eliminate cause of
problem.
b. Never wrap periphery
of fusible link with vinyl
tape.
Extreme care
should be taken with this link
to ensure that
it does not
come into contact with any
other wiring
harness
or vinyl
or rubber pans.

BATTERY
CAUTION:
a. lf
it
becomes neoessary to start the engine with
a booster
battery and jumper
cables, use a 12-volt
booster battery.
b. After
connec-ting battery cables,
ensure that they are tightly
clamped to batlery
terminals lor good
contact.
How to Handle
Battery
METHODS OF PREVENTING
OVER-DISCHARGE
The following precaulions
must be
taken to prevent
overdis-
charging a battery.
o The
battery surface (particularly
ils top) should always
be
kept clean and
dry.
lf the top surface of
a battery is
wet wilh electrolyte
or
water, leakage
current will cause the
battery to discharge.
Always keep
the battery
clean and dry.
When the vehicle is not going
to be used over a long period
ol time, disconnect the negative
battery terminal. (ll
the
vehicle has an extended storage
switch, turn it off.)
Check the charge
condition of the battery.
Periodically check the
specific gravity
of the
electrolyte.
Keep a close check
on charge condition
to prevent
over-
discharge.
CHECKING ELECTROLYTE
LEVEL
WARNING: Do not allow battery fluid
to come in contact with
skin, eyes,
fabrics, or painted
surfaces, After touching a
battery, do not
touch or rub your
eyes until you
have thoroughly washed your
hands. lf the
acid contacts the eyes,
skin or clothing, immedi-
ately flush with
water for 15 minutes
and seek medical atten-
tion.
Normally the
battery does not require
additional water.
However, when the
battery is used under severe
condilions,
adding distilled water may be necessary
during the battery life.

SULPHATION
When a baftery has
been left
unattended for a long period
of
time and has a specific gravity
ot less than 1.100, it will
be
completely discharged, resulting in sulphation on
the cell
plates.
Compared with a battery discharged under normal conditions,
the current flow in a "sulphated"
battery is not as smooth
although its voltage is high
during the initial
stage of charging,
as shown in
the figure
at the left.
SPECIFIC GRAV]TY CHECK
1 . Read hydrometer and thermometer indications
at eye level.
o When
electrolyte level is
too low,
tilt battery case to raise it
for easy measurement.
2. Convert into
specitic gravity
at 20'C (68"F).
Examole:
o When
electrolyte temperature is
35"C (95'F)
and specific
gravity of electrolyte is 1 .230, converted specific gravity
at
20'C (68'F)
is 1.240.
o When
electrolyte
temperalure is
0"C (32"F)
and specific
gravity of electrolyte is 1 .210,
converted specific gravity
at
20'C (68'F)
is 1 .196.
