w iring 
connec tions and  if  necessary , replace the switch. 
NOTICE ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
Never insert the tester probes into the coupler terminal slots a. Always insert the probes from 
the opposite end of the coupler, taking care not to loosen or damage the leads.

AwARNING 
Since the headlight bulb gets extremely hot, 
ELECTRICAL  COMPONENTS 
keep flammable products and your hands 
away 
from the bulb until it has cooled down. 
NOTICE 
• Be  sure to hold the socket firmly when  re­
moving the bulb. Never pull the lead, other­
wise it may be pulled out of the terminal in 
the coupler. 
• 
Avoid touching the glass part of the  head­
light bulb to keep it free  from oil, otherwise 
the  transparency 
of the glass, the life of the 
bulb, and  the luminous flux will be adverse­
ly affected. If the headlight bulb gets soiled, 
thoroughly it with a cloth moistened with al­
cohol or lacquer thinner.

CHECKING AND CHARGING THE BATTERY 
AwARNING 
Batteries  generate explosive hydrogen gas 
and contain electrolyte which is made of poi­
sonous and highly caustic sulfuric acid. 
Therefore, 
always follow these  preventive 
measures : 
• Wear protective  eye gear  when handling or 
working near batteries. 
• Charge  batteries in a well-ventilated area. 
• Keep  batteries  away from fire, sparks or 
open flames (e .g., welding equipment , 
lighted cigarettes). 
• DO NOT SMOKE when  charging or han­
dling batteries . 
• KEEP  BATTERIES AND 

ELECTROLYTE 
OUT OF REACH OF CHILDREN. 
•Avoid bodily contact with electrolyte as it 
can  cause  severe burns or permanent  eye 
injury. 
FIRST  AID IN CASE  OF BODILY CONTACT: 
EXTERNAL 
•  Skin - Wash  with water. 
• Eyes -Flush with water for 15 minutes and 
get  immediate 
medical attention. 
INTERNAL 
• 
Drink large quantities of water or milk fol­
lowed with milk of magnesia , beaten  egg or 
vegetable  oil. Get immediate medical  atten­
tion. 
NOTICE ~~~~~~~~~~~~~ 
• This is a VALA (Valve  Regulated Lead Acid) 
battery.  Never remove 
the sealing caps be­
cause  the balance between cells will not be 
maintained  and battery  performance will 
deteriorate. 
• Charging  time, charging  amperage  and 
charging voltage for a VALA (Valve  Regu­
lated 
Lead  Acid)  battery  are different from 
those of conventional batteries.  The VALA 
ELECTRICAL  COMPONENTS 
(Valve Regulated Lead Acid)  battery should 
be charged  according to the appropriate 
charging method. If the battery is over· 
charged,  the electrolyte  level will drop con­
siderably. Therefore , take special care 
when  charging  the battery. 
TIP~~~~~~~~~~~~~~­
Sinc e VRLA (Va lve Regulat ed Lead Acid) bat­
teries  are 
sealed, it  is  not poss ible to  check  th e 
charge  state 

o f  the  battery  by measuring  th e 
speci
fic  gravity  of the elec trolyte. Theref ore,  th e 
cha
rge  of  the  battery  has to  be  checked  by mea­
suri

AwARNING 
Do not quick charge  a battery . 
NOTICE ~~~~~~~~~~~~~~ 
• Do not use a high-rate  battery charger 
since it forces a high-amperage current 
into the  battery quickly and can  cause  bat-
ELECTRICAL  COMPONENTS 
tery overheating and battery plate damage. 
• If it is impossible to regulate the charging 
current on the  battery  charger, be careful 
not to overcharge  the battery. 
•When charging a battery , be sure to remove 
it from the vehicle. (If charging has to be 
done with the battery mounted on the vehi· 
cle, disconnect the negative battery lead 
from the battery terminal.) 
• To reduce  the chance of sparks, do not 
plug in the battery charger until the battery 
charger leads  are connected to the  battery. 
• Before  removing the battery charger lead 
clips from the battery  terminals , be sure to 
turn off the battery charger. 
• Make sure the battery charger lead clips are 
In full contact with the  battery  terminal and 
that they are not shorted. A corroded bat­
tery charger lead clip may generate heat in 
the contact area and a  weak clip spring may 
cause sparks. 
• If the battery becomes hot to the touch at 
any time during the charging process, dis­
connect the battery charger and let the bat­
tery cool before reconnecting  it. Hot 
batteries can explode! 
• As shown in the following illustration, the 
open-circuit voltage of a VRLA  (Valve Reg­
ulated  Lead Acid) battery  stabilizes about 
30 minutes after charging has been com­
pleted. Therefore , wait 30 minutes after 
charging is completed  before measuring 
the open-circuit voltage .
