1.3 LEGEND FOR CIRCUIT DIAGRAM
1.3.1 BATTERY
A. DEFINITION
The condition that the electric energy is produced from
the battery is called “electric discharge” and the cur-
rent discharged in this case is called “discharge
current”. The condition that the electric energy is sup-
plied to the battery is called “recharge” and the current
supplied in this case is called “charging current”.
The alternator supplies the battery with electric energy
or recharges the battery.
This tractor is equipped with a 12 V battery with mini-
mum cold cranking ability of 630 A at -18°C.
The battery is located under the hood in front of the
radiator. It should be firmly fixed in place with a reten-
tion holder.
If the battery terminal is corroded, clean it with a baking
soda solution.
After cleaning, rinse the battery and apply a small
amount of grease to prevent the terminals from
corroding.
The battery should maintain its charge even at or be-
low freezing. If the battery is discharged or the battery
fluid is low, the electrolytes may be diluted or frozen.
This may damage the battery. If any water is added,
use only distilled water.
Add water before using the tractor. This allows the elec-
trolytes to mix with the water so that the water does not
freeze.

B. CAUSE OF BATTERY EXPIRATION
The causes for battery failure can be divided into the
following three parts:
1. OVERLY DISCHARGED
The specific gravity of electrolyte is too low and the
terminal voltage is not measurable.
CAUSES
•
Self-discharge:
If the battery is left unused for 2 ~ 3 months, it will
fully discharge.
•
Closed circuit (battery surface):
Due to electrolyte or water on the battery cover, a
closed circuit may form between the positive and
the negative terminals and, consequently, the bat-
tery will fully discharge.
2. OVER CHARGING
If the battery is charged too long, the electrolyte’s tem-
perature rises and the amount of electrolyte may
evaporate.
(If this happens frequently, the battery life is shortened.)
3. BATTERY LIFE
If the charged and discharged conditions are repeated,
the amount of activated material and the specific grav-
ity decreases due to chemical reactions between the
positive terminal, negative terminal and electrolyte.
