Stator
• Using ohmmeter, check all leads for continuity. If there is no continuity, replace stator (1).
• Using ohmmeter, check that there is no continuity between coil leads (2) and stator core (1). If there is continuity,
replace stator.
Brush and brush holder
Check each brush for wear by measuring its length. If brush is found worn down to service limit, replace brush.
Brush length “a”
Standard: 16 mm (0.63 in.)
Limit: 5 mm (0.20 in.)

Rectifier
1) Using ohmmeter, check continuity between each of upper and lower rectifier bodies and each diode lead (2).
Check both directions by reversing probes of ohmmeter and there should be only one-way continuity in each case.
If check result is not satisfactory, replace rectifier (1).
2) In the same manner as described in above Step 1), check that there is only one-way continuity between both leads
of diode trio.
Condenser
Check condenser capacity.

General Description
Battery Description
S6JB0A1A21001
The battery has three major functions in the electrical
system.
• It is a source of electrical energy for cranking the
engine.
• It acts as a voltage stabilizer for the electrical system.
• It can, for a limited time, provide energy when the
electrical load exceeds the output of the generator.
Carrier and Hold-Down
The battery carrier should be in good condition so that it
will support the battery securely and keep it level.
Before installing the battery, the battery carrier and hold-
down clamp should be clean and free from corrosion and
make certain there are no parts in carrier.
To prevent the battery from shaking in its carrier, the
hold-down bolts should be tight enough but not over-
tightened.
Electrolyte Freezing
The freezing point of electrolyte depends on its specific
gravity. Since freezing may ruin a battery, it should be
protected against freezing by keeping it in a fully
charged condition. If a battery is frozen accidentally, it
should not be charged until it is warmed.
Sulfation
If the battery is allowed to stand for a long period in
discharged condition, the lead sulfate becomes
converted into a hard, crystalline substance, which will
not easily turn back to the active material again during
the subsequent recharging. “Sulfation” means the result
as well as the process of that reaction.
Such a battery can be revived by very slow charging and
may be restored to usable condition but its capacity is
lower than before.
Care of battery
WARNING
!
• Never expose battery to open flame or
electric spark because of battery generate
gas which is flammable and explosive.
• Do not allow battery fluid to contact eyes,
skin, fabrics, or painted surfaces as fluid is
a corrosive acid. Flush any contacted area
with water immediately and thoroughly.
• Batteries should always be kept out of
reach of children.
1) The battery is a very reliable component, but needs
periodical attentions.
• Keep the battery carrier clean.
• Prevent rust formation on the terminal posts.
• Keep the electrolyte up to the upper level
uniformly in all cells.
• When keeping battery on vehicle over a long
period of time, follow instructions given below.
– Weekly, start the engine and run it until it
reaches normal operating temperature with
engine speed of 2000 to 3000 rpm. Make sure
all electric switches are off before storing the
vehicle.
– Recharge the battery twice a month to prevent
it from discharging excessively. This is
especially important when ambient temperature
is low.
The battery discharges even when it is not
used, while vehicles are being stored. Battery
electrolyte can freeze and battery case can
crack at cold ambient condition if battery is not
properly charged.
2) Keep the battery cable connections clean.
The cable connections, particularly at the positive (+)
terminal post, tend to become corroded. The product
of corrosion, or rust, on the mating faces of
conductors resists the flow of current.
Clean the terminals and fittings periodically to
ensure good metal-to-metal contact, and grease the
connections after each cleaning to protect them
against rusting.
3) Be always in the know as to the state of charge of
the battery. The simplest way to tell the state of
charge is to carry out a hydrometer test. The
hydrometer is an instrument for measuring the
specific gravity (S.G.) of the battery electrolyte. The
S.G. of the electrolyte is indicative of the state of
charge. Refer to “Hydrometer Test” in “Battery
Inspection: For Diesel Engine Model”.
