Here you can find new Voltage Regulators for classic, American cars. The voltage regulator is the "brain" of your car's electrical system. It carefully controls the amount of generator voltage for charging your battery and operating electrical components. Too much voltage and you drastically shorten the life of your generator and battery. Too little voltage drains your battery and can leave you stranded.
