5. Check electrolyte level in battery. If battery will not take adequate charge, or is otherwise unsatisfactory replace battery.
When the alternator is charging the battery, an explosive gas is produced inside the battery. Therefore always check the electrolyte level with the engine stopped. Do not use an exposed flame and do not smoke while checking the battery. 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.
6. Check the alternator fuse intact or not.
Charging Circuit Should the battery be 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.
Check the alternator fuse intact or not.
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 before carrying out arc welding on the tractor or any implement attached to the tractor.
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.
