ABSTRACT:
A short detection circuit and method for operatively controlling current in an electrical load such as an alternator field coil includes a driving device such as a Darlington transistor for driving the electrical load. Detecting means selectively withhold and provide operating current to the driving means when a shorted and not shorted condition of the electrical load is respectively detected at the driven terminal of the driving device.
