Alternator Voltage Regulator 12V Delco 10SI Internal Straight Pins Chevrolet Impala Malibu Cadillac 1980-1985 REG2004
Alternator Voltage Regulator 12V Delco 10SI Internal Straight Pins Chevrolet Impala Malibu Cadillac 1980-1985 REG2004
Vehicle Compatibility
Alternator voltage regulator for Delco 10SI internal regulator alternator applications using straight pins and a 2 pin IG B(+) connection. This regulator is specified as an A-circuit design with IR/EF (internal regulator / external fan) configuration and an inactive lamp specification, commonly used across a wide range of General Motors and industrial alternator builds. Vehicle and equipment coverage is typically confirmed by alternator series (10SI) and plug layout rather than model alone. Confirm by alternator label and pin layout before ordering.
