5 & 9 Amp Regulated Alternator
The 5 & 9 amp regulated alternator systems provide
AC current through a
regulator-rectifier. The regulator-rectifier converts the
AC current to DC and regulates current to the battery.
The charging rate will vary with engine RPM and
temperature.
Alternator output is determined by the flywheel
alternator magnet size.
regulator-rectifier are the same for the 5 & 9 amp
regulated system and the Tri-Circuit system.
