Condition of Battery
Starter does not function
From beginning, starter does not
function, and lights become dim
quickly
Low electrolyte level
Battery cannot be charged
Corrosion of terminals is severe
Electrolyte decrease rapidly
- K e y i s n o t “ O N ”
- Battery is over-used until light
becomes dim.
- Charging of battery neglected
defective alternator rectifier.
- Dirty or corroded terminal
contacts.
- Bad brushes, armature or field.
- Life of battery expired.
- Battery is not charged well.
- Battery used with shortage of
electrolyte.
- Battery over-used. Moreover,
charging was neglected (Refrain
from over-discharging).
- Defective alternator rectifier,
defective terminal contacts
causing sulphation of electrodes.
- The current of the alternator
during operation is too high
causing plates to drop, warp or
short circuit.
- Life of battery expired.
- Current of the Alternator during
operation is too large.
- Over heating due to over
charging.
- Storage battery cracked or has
small holes.
Cause
- Turn key “ O N ”
- Charge for long period by ordinary
charging method until specific
gravity of 1.26 is reached.

defective rectifier.
- Charge battery well.
- Wash terminal with hot water and
tighten well.
- Replace.
- Replace battery.
- Charge battery for a long period
by ordinary charging method.
- Add distilled water and charge
battery.
- Charge for a long period.
- Check alternator and rectifier and
charge for a long period by
ordinary charging method.
- Decrease the charging current of
alternator.
- Exchange defective battery.
- Exchange battery.
- Clean scale from terminals and
tighten well.
- Adjust charging current of
alternator.
- Check charging output.
- Replace battery.
Countermeasures
- Do not overuse the battery and
charge before fully discharged.
(Refrain from over discharging)
- Check alternator rectifier.
- Keep terminals clean, tighten well
and grease to prevent corrosion.
- Battery must be serviced properly
before initial use.
- Make routine checks of
electrolyte.
- Do not overuse the battery and
fully discharge.
- Make routine checks of terminals,
to make sure they are clean and
tight.

Alternator.
- Keep terminals clean and well
tightened. Apply grease to
prevent corrosion.
- Check charging current of
alternator.
- Secure battery to tractor so it
would not move.
