 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.
