Briggs & Stratton engines are equipped with a
number of different alternator systems to meet the
requirements of equipment manufacturers. For
example, a large lawn tractor with accessories may
require a 16 amp regulated system, whereas a snow
thrower with a single headlight requires an AC Only
system. Knowing the type of alternator system an
engine is equipped with is important, particularly
when an engine is being replaced.
Briggs & Stratton alternator systems are easily
identified by the color of the stator output wire(s) and
the connector.
