7. TROUBLE SHOOTING AND CORRECTIVE ACTION
Tro ub le
A. Sulfation
The elect rod e plates are
covered with white la yer
or in spots !Fig. 5-20).
B. Self discharge
Battery discharges in addi -
tion to that caused by the
connected load.
C. Discharge rate large
Specific gravit y, gradually
lowers and ar o und 1.1, the
turn s ignal lamp and horn
no
long er function.
D.
High charging rate
The electrolyte l evel dr o ps
rapidl y but the charge is
always maintained at 10 0 %
and the condition appears
satisfactory. A condition
which is overlooked . (spe-
cific gravity over 1.2601
E. Specific gravity drops
Electrolyte evaporates
Probable cause
1. Charging ra te is too sm all or else
excessi
vely la rge.
2. Th e specific gravit y or the mixture
of the elec t rolyte is improper .
3.
Battery l eft in a d ischarged condi-
t ion f or a long pe rio d. !left with
the sw
it(h turned on )
4. Exposed
to excess iv e vi br at i on due
to im pr op er in stalla tion .
5. Dur
in g c ol d season wh en mot or-
cy cle is le fi s to re d, the wi ring
should be di
sc onn ected.
1.
Dirty contact areas and case.
2.
Contaminated el ectrolyte or elec-
troly
te excessively concentra ted.
1. The fuse
and the wiring is satis-
fac t ory; the loads such as turn signal
lamp
and ho rn does not function.
In this condi t ion the motor c ycle will
operate but w ith p ro l ong us e, both
the EB and 8 plates wi ll react
wit h the sulfuric aci d and form lea d
su l fide deposits, lsulfati onl mak in g
it impossible to recharge .
1. The
deposit wil l heavi ly accumulate
at the
bottom and wi ll cause inter-
nal sh or ting, causing damage to th e
ba
tt ery.
1.
Shorted
2. Insufficient char ging
3. Dtst ill ed wate r ove r-fill ed
4. Con t aminated electrol y te
C orr ect act i on
1. Whe n s tor ed in a dischar ged cond i-
tion , the ba tt e ry should be rechar g-
ed o nce a month even wh en the
m
oto rcycle is not - us ed.
2.
Check the elect rol yte per i od i ca lly
and alw ays main ta in the proper
- level, 10-13 mm (0 .400 - 0.518 in.l
above the plates.
3.
In a lig htly dischar ge d c on dition,
the ba t ter y may be rest ored by
overcharging at 20H.
Depending upon the c on di tio n, per -
f
orm ing recharging and discharging
se v era l tim es may be sufficient.
1. Always maintain
the exterio r clea n.
2.
Ha ndle the r eplenishing flu id with
care.
1. W hen the
speci fic grav it y falls
below 1, 200 1 20°C : 68°FI, the ba t-
tery should
be r echarged i mm e-
di
ate ly.
2.
When the ba ttery fr eque ntly be -
comes disc
har ged wh il e opera ting
at normal speed, check the ge ne r-
at or f or pr oper ou tput.
3.
If the ba t te ry discharges un der
normal char ge output, it is an indi-
cat ion of over l oading, rem ove some
of
the excess load.
1. Check to assure prope r cha rg ing
rate .
2. W hen
ove rcharge cond it io n exi st
with the pr oper charging rate , place
an appropr iate resistor in the charg-
ing circuit.
1.
Perform speci fic gravi ty meas ur e-
ment.
2.
If the add it ion of distilled wa ter
causes a dr op in spe cific gravity,
add sulfuric ac id and adjust to
prope r specific gr a vi ty.
