Land Rover Part Number: AMR4247 - Alternator A127 - 100A - V8 EFI
AMR4247 is an Alternator A127 - 100A - V8 EFI. Fitted to the charging system of 4.0 V8 EFI petrol engines, this 100 amp alternator converts mechanical input from the engine pulley into electrical power to recharge the battery and supply the vehicle's electrical systems while the engine runs. The A127 design provides the higher output required by V8 EFI applications; correct belt alignment and tension and clean, secure electrical connections are required at installation to maintain charging performance and avoid premature bearing wear or voltage drop. Replacing like-for-like with a 100 amp unit preserves the vehicle's original charging capacity and electrical system behaviour. Use the compatibility data below to confirm fitment against your V.I.N.
