Battery Servicing; Electrolyte Adjustment; Recharging Operation Based On S.g. Reading - Suzuki GS850G Service Manual

ELECTRICAL SYSTEM
4. Bectrolyfe adjustment
After charging re-check the electrolyte S.G.
to make sure it is 1.280 corrected for 20°C
(68°F). Add distilled water,
if necessary, to
ad just the S.G. of
each cell. Replace the caps,
and
wash
the
surfaces
of the battery container
with fresh water. Let the battery dry before
mounting
it on
the motorcycle.
R ATTERY SERVICING
Removal
1. Lift u p the seat and open the
too1 hol,,,
.
2. Disconnect the lead wires from both
positive and negative plates.
3. Disconnect
the breather hose
from the
battery.
4. Remove the band remove the battery from
the battery holder.
Installatian
Before mounting the battery, make sure that
the exterior
surface of
the battery container is
dry and free from electrolyte. Be careful not
to
forget to re-connect the battery breather
hose. The installing procedure is the reverse
Inspection
1. Visually inspect the surface of the battery.
If signs of cracking or electrolyte leakage
from the sides o f the battery are noticed,
replace the battery
with
a new one.
2. I f the battery terminals are found to be
coated
with rust or
an acidic
white
powdery substance, then this
can be
cleaned
away
with sandpaper or hot water,
respectively.
3. Check the electrolyte level and add distilled
water, if necessary, to raise
the
electrolyte
in each cell to the upper level.
Check
t h e
Dattery for proper charge by
takirtg
an electrolyte S.G. reading. If the
reading is 1.200 or less,
corrected Tor 20°C
(6HWF), i t means that the battery
i s
run-
down and needs recharging.

reading
To correct on S.G.
reading
for 20°C (6R°F),
use this formula:
Sm
=
St + 0.0007
( t
-
20)-
where S , ,
=
corrected value of S.G. (20°C or

St

and
t =

To read the S.G. on
the hydromcrer, bring
the
electrolyte in the hydrometer
to
eye level
and read the graduation an the float scale
corresponding to
the meniscus (curved
