Abstract
The alternator on an engine has a set of stator coils which are connected to supply current to power accessories and current for a battery charger when the engine is running. When the ignition is turned off, a braking switch is closed which short circuits the stator coils. The resulting high current in the stator coils produces a braking torque on the engine shaft that brings it and any attached implement to a rapid halt.
