Abstract
A method and system are disclosed for limiting the voltage provided by a generator in the event of a regulator or field coil short circuit failure in an automotive vehicle. The voltage provided by the generator is sensed and a corresponding voltage level is generated. The voltage level is then compared to a predetermined voltage threshold. If the voltage level exceeds the predetermined voltage threshold, the high-side field coil switch is cycled by the controller so as to control the voltage provided by the generator. The electronic components of the vehicle are protected from over-voltage damage, and the battery is prohibited from overcharging.
