Alternator Voltage Regulator Holden VL VN VP VR VS VT VQ / Ford EA EB ED EF EL XG - RE60

Built for Holden 1986 – 2000 Commodores, along with Ford 1988 – 1998 Falcon models, the Alternator Voltage Regulator is a vital internal component designed to maintain stable electrical output from Bosch-style alternators. Engineered as a brush-box style regulator, it not only controls charging voltage but also houses the alternator brushes — a common wear item in many Australian-built vehicles of this era. Ideal for resolving charging faults such as flickering battery warning lights or inconsistent voltage, this regulator restores proper alternator performance and reliable battery charging.

Key Features

• Brush-Box Style Regulator Design: Combines voltage regulation and brush holder assembly into one compact, serviceable unit.
• Stable Charging Control: Regulates alternator field current to maintain battery voltage typically between 13.8V and 14.4V, helping prevent overcharging or undercharging.
• Integrated Carbon Brushes: Features two carbon brushes that maintain consistent contact with the alternator slip rings.
• Direct Drop-In Fitment: Designed as a direct replacement module for compatible Bosch alternators, allowing straightforward installation.
• Restores Charging System Performance: Helps ensure reliable battery charging and stable operation of vehicle electrical systems.
