Abstract
The system is directed to preserving an IC engine installation from potential overload and failure in response to electrical load increases passed along by an associated engine driven digitally controlled starter/alternator. The system controller monitors starter/alternator output and phase current and/or regulates the rate of change of output current in response to increasing electrical load. In an instance where monitored rates of output current change exceed predetermined thresholds, the response rate of the starter/alternator, i.e., rate of change of output current, is set at a predetermined threshold so as to prevent the braking effect of the increasing electrical load from stalling the I.C. engine or causing other operational failure.
