1. A method for controlling a generator, comprising:
- (a) generating a first signal indicative of an electrical potential across a conductor included in the generator, said conductor comprising a process-controlled geometric shape, and wherein a total electrical output current generated by the generator is substantially proportional to the electrical potential;
(b) generating a second signal indicative of a temperature of the conductor; and
(c) at least one of limiting and ceasing the total electrical output current, via a generator output power controller, according to at least one the first and second signal.

Abstract
A control device measures a voltage drop across a conductor in a generator to determine and control the total generator output current. A temperature of the conductor is also measured to improve the accuracy. The control device may further improve on the accuracy by compensating for the electrical current through a field coil that may power the generator. The control device may be used in combination with a generator in a vehicle electrical system. Other system parameters may be monitored to improve on the system monitoring, diagnostics, and control. The generator may include a conductor comprising a process-controlled geometric shape.
