Electrical System
To avoid damage to alternator charging system,
service precautions should be observed as
follows,
1. Never make or break any of the charging
circuit connections, including the battery
when engine is running.
2. Never short any of the charging
components to ground.
3. Do not use a jumper battery of higher than
12 volts.
Always disconnect the battery ground cable
before carrying out arc welding on the tractor
or any implement attached to the tractor.
Use only specified cable for replacement
Should the starter motor be removed, and a
replacement motor or drive end bracket be
fitted, a check must be made of the out of
mesh clearance after assembling the starter
motor to the engine. The dimension between
the leading edge of the pinion and the engine
flywheel should be no less than 0.32 cms.
Alternator
Following checks of alternator charging system will avoid
many problems that might otherwise develop.
1. Check belt tension. Refer your operator’s manual
(page no. 57) for proper belt tension.
2. Keep pulley nut tight.
3. Check alternator terminals and cable connections for
good condition, secure fastening and freedom from
corrosion.
4. Check battery cables and connections for good
condition, secure fastening and freedom from
corrosion.
5. Check electrolyte level in battery. If battery will not take
adequate charge, or is otherwise unsatisfactory replace
battery.
Charging Circuit
If the battery is in a low state of charge, which will be
shown by lack of power when starting, poor lights and
hydrometer readings below 1.200 and may be due to either
alternator not charging or giving lower intermittent output,
then proceed as below :
Check Battery Charging Indicator when the engine is
running steadily at working speed.
If the Battery Charging Indicator glows, have the
equipment checked by your Mahindra tractor dealer.
Inspect alternator drive belt and adjust as necessary.
Examine the charging and field circuit wiring, tighten
any loose connections, replace any broken cables, pay
particular attention to the connections.
Starter Motor Removal
1. Disconnect the battery to starter solenoid coil cable,
earth cable from the battery, Key Switch to solenoid coil
cable.
2. Remove the mounting bolts and withdraw the starter
motor. To install the starter motor, reverse the above
procedure.
Note : Alternator Maintenance should be done
by authorised dealer.
Too tight a belt will cause rapid wear of belt and
damage to bearings.
A slack belt will not drive the Alternator, and
therefore the battery will not be charged.
