REGULATOR_FOR_ALTERNATOR

Simple and effective solid-state replaeement for auto voltage regulator can be used with altemator in almost any negative-ground system. Circuit acts as switch supplying either full or no voltage to field winding of altemator. When battery is below 13 V, zenel D1 does not conduct, Q1 is off, Q2 is on, and full battery voltage is applied to alternator field so it puts out full voltage to battery forcharging. When battery reaches 13.6 V, Q1 tums on, Q2 tums off, altemator output is reduced to zero, and battery gets no charging current. Corcuit can also be used with wind-drivent alternator systems.-P.S.Smith, $22 for a Regulator? Never!, 73 Magazine, Holifay issue 1976, p 103.
