An apparatus and method are provided to deliver an output signal indicative of engine rotational speed and/or generator rotational speed. The output signal preferably is delivered to, or developed internally and used by, a voltage regulator. The output signal can be generated based on a ripple on a positive voltage input to the voltage regulator from a generator. A charging system containing such a voltage regulator and/or apparatus also is provided. Use of this apparatus and method advantageously circumvents the need for a separate connection between one or more phases of the generator (e.g., taken from an AC input to a bridge rectifier of the generator) and the voltage regulator, which connection typically was heretofore required by voltage regulators that are load-responsive or otherwise operate in a manner dependent upon the rotational speed of the generator and/or engine.
