Mahle - MG29 - Alternator Fendt F731900010070

This alternator converts mechanical energy from the engine into electrical energy to charge the battery and power the tractor's electrical loads. It is mounted on the engine and driven by the accessory belt. The internal voltage regulator maintains the system voltage at a set level. A failing alternator typically causes a low battery warning, dimming lights, or a no-start condition. The manufacturer produces this unit with the same pulley alignment and mounting bracket geometry as the original assembly, so no adapter plates or belt realignment are needed.
