Voltage regulators are critical components that monitor battery voltage and control alternator field current to maintain proper charging voltage typically between 13.5-14.5 volts. When a voltage regulator fails, symptoms can include undercharging, overcharging, flickering lights, or battery warning lights. This Bosch replacement regulator restores proper voltage control to keep your vehicle's electrical system operating reliably.
