Charging System Voltage Regulator for Classic Pontiac

Standard Ignition VR-104 is a 12-volt charging system voltage regulator built for classic Pontiac applications with ammeter-equipped charging systems. It is a direct-fit electrical service part for restoring stable alternator output in select 1963-1968 Pontiac Catalina, Bonneville, Grand Prix, and Tempest models.

Key Features

• 12-volt charging system voltage regulator
• Female connector gender with 3 male blade terminals
• Universal mounting location
• Encapsulated electronic circuit board for improved resistance to vibration and corrosion
• Premium materials selected for extended service life
• Standard Ignition VR-104 for OE-style charging system service

Detailed Description

The Standard Ignition VR-104 is engineered for precise voltage regulation in older alternator-equipped Pontiac charging systems. Its electronic design uses a circuit board encapsulated in epoxy to improve durability and reduce failure risk from vibration and corrosion at electrical connections. This makes it a practical replacement for restoring consistent charging performance in 1963-1968 Pontiac Catalina, Bonneville, Grand Prix, and Tempest vehicles with ammeter setups. Standard Ignition VR-104 is backed by the brand’s manufacturing control from component selection through final assembly, supporting dependable electrical service in classic vehicle applications.

This part cross-references 1V1251 and VR140 for the same application.
