BATTERY TROUBLESHOOTING

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
Cause
- Key is not "ON"
- 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 dur-
ing operation is too high caus-
ing 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.
Countermeasure
- Turn key "ON"
- Charge for long period by ordi-
nary charging method until spe
cific gravity of 1.26 is reached.
- Repair alternator and replace
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.
Cause
- Do not overuse the battery
and charge before fully dis-
charged. (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.
- Check charging current of
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.
