Mahle - 37810011 - Regulator 14V

This voltage regulator controls the alternator output to maintain a stable system voltage for the electrical loads on the host tractor. It is mounted on the engine and regulates the field current of the alternator, preventing overvoltage conditions that can damage batteries and sensitive electronic controls. A failed regulator typically results in an undercharged battery or flickering lights, as the alternator output becomes erratic. The component is manufactured to match the mounting dimensions and electrical interface of the original assembly, ensuring correct plug connection and heat dissipation through the alternator housing.
