What does an alternator regulator do?

Setup, Compatibility & Care
To install this regulator, ensure the vehicle's battery is disconnected to prevent short circuits. Locate the alternator at the rear of the engine bay, remove the protective cover, and replace the existing regulator assembly with the Hella unit. Always verify your alternator manufacturer markings before installation; if your vehicle is equipped with a Lucas alternator, this part will not be compatible. Keep the area around the alternator free of oil and debris to ensure proper heat dissipation and electrical contact.
