Abstract
Abstract An annular alternator stator core, mounted on the body of a small gasoline engine concentrically to a rotatable shaft that carries permanent magnet means, has two windings, each extending circumferentially about halfway around it. At one side of the core adjacent ends of the two windings are grounded to it. Leads extend from the other ends of the windings to nearby sockets fixed accessibly on the engine. One socket is an a.c. terminal; the other, comprising one terminal of a source of unidirectional battery charging current, can be a conventional fuseholder containing a novel readily replaceable diode unit.
