Bosch Voltage Regulator

The Bosch voltage regulator (also called an alternator regulator) controls the charging output of your alternator. It keeps system voltage steady so the battery stays charged and the vehicle's electrical components get stable power.

Key Features:

• Regulates alternator output to protect the battery and electrical system from overcharging and undercharging
• Built to Bosch's OE-supplier standards for reliable, consistent performance
• Designed for long service life under heat, vibration and changing electrical loads
• Helps keep headlights, ignition, electronics and accessories running smoothly
• Direct-replacement design for straightforward installation

Bosch has supplied charging-system components to automakers for decades. A new regulator can restore proper charging when you see symptoms like a dim or flickering battery light, an undercharged or overcharged battery, or erratic electrical behavior. Choose the variant that matches your alternator.
