Abstract
The system is directed to preserve the starter/alternator in an IC engine installation from potential overload and failure in response to electrical load increases. The system controller monitors starter/alternator output and phase current and regulates output voltage when monitored currents reach predetermined thresholds. Output voltage is stepped down incrementally to check output currents at threshold non-failure creating levels. When current demand, i.e., load, decreases, output voltage is stepped up incrementally to return to an original set point for voltage.
