CHARGING SYSTEM
PRECAUTION
1. Check that the battery cables are connected to the
correct terminals.
2. Disconnect the battery cables when the battery is
given a quick charge.
3. Never disconnect the battery while the engine is
running.
4. Check that the charging cable is tightly connected to
terminal B of the generator.

ON-VEHICLE INSPECTION
CAUTION:
If the battery is weak or if the engine is difficult to start,
recharge the battery and perform the inspections again
before returning the vehicle to the customer.
1. CHECK BATTERY CONDITION
(a) Check the battery for damage and deformation. If
severe damage, deformation or leakage is found,
replace the battery.
(b) Check the volume of electrolyte in each cell.
(1) For batteries that are maintenance-free:
• If the electrolyte volume is below the lower
line, replace the battery.
• If the electrolyte volume is above the lower
line, check the battery voltage when
cranking the engine.
• If the voltage is less than V, recharge or
replace the battery.
HINT:
Before checking the battery voltage, turn off all
the electrical systems (headlights, blower
motor, etc.).
(2) For batteries that are not maintenance-free:
• If the electrolyte volume is below the lower
line, add distilled water to each cell. Then,
recharge the battery and check the specific
gravity of the electrolyte.
Standard specific gravity:
CH to at 20 °C ( 68 °F)
If the electrolyte volume is above the lower line,
check the battery voltage when cranking the
engine. If the voltage is
