GENERAL DESCRIPTION

BATTERY

The battery has three major functions in the electrical system.

D It is a source of electrical energy for cranking the engine.

D It acts as a voltage stabilizer for the electrical system.

D It can, for a limited time, provide energy when the electrical load

exceeds the output of the generator.

The battery mounted in each vehicle is the following type.

38B20R TYPE

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 fro-

zen 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, crystal-

line substance, which will not easily turn back to the active material

again during the subsequent recharging. “Sulfation” means the re-

sult 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

1) The battery is a very reliable component, but needs periodical

attentions.

Keep the battery carrier clean; prevent rust formation on the ter-

minal posts; keep the electrolyte up to the upper level uniformly

in all cells.

When keeping battery on vehicle over a long period of time, fol-

low instructions given below.

D Weekly, start the engine and run it until it reaches normal op-

erating temperature with engine speed of 2000 to 3000 rpm.

Make sure all electric switches are off before storing the ve-

hicle.

D Recharge the battery twice a month to prevent it from dis-

charging excessively. This is especially important when am-

bient temperature is low.

The battery discharges even when it is not used, while ve-

hicles 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 cur-

rent.

Clean the terminals and fittings periodically to ensure good met-

al-to-metal contact, and grease the connections after each

cleaning to protect them against rusting.

WARNING:

D Never expose battery to open flame or electric spark

because of battery generate gas which is flammable

and explosive.

D 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 thor-

oughly.

D Batteries should always be kept out of reach of chil-

dren.

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 measur-

ing the specific gravity (S.G.) of the battery electrolyte. The S.G.

of the electrolyte is indicative of the state of charge. Refer to

“BATTERY” of DIAGNOSIS in this section.

GENERATOR

The generator is a small and high performance type with an IC regulator incorporated.

The internal components are connected electrically as shown below figure.

The generator features are as follows:

D Solid state regulator is mounted inside the generator.

D All regulator components are enclosed into a solid mold.

D This unit along with the brush holder assembly is attached to the rear housing.

D The IC regulator uses integrated circuits and controls the voltage produced by the generator, and the voltage

setting cannot be adjusted.

D The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication. Two brushes

carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions will

provide long period of attention-free service.

D The stator windings are assembled on the inside of a laminated core that forms part of the generator frame.
