This solid state voltage regulator is
designed specifically to fit standard output three brush GAS model Autolite
generators using a 6 volt negative ground system, positive field winding
control and external cutout relay (Standard equipment on Indian motorcycles
from 1930 through 1947).
CONSTRUCTION: The sold state regulating
components are permanently mounted inside an anodized aluminum housing. This
housing is CNC milled to look exactly like the original stamped cover,
including accurate �AUTOLITE made in u.s.a.� lettering. The housing also acts
as a heat sink for the internal components. This housing is mounted on a
cadmium plated reproduction of the original base. The end result is a
reliable, maintenance free, modern electronic regulating system housed in an
exact replica of the original style cutout relay housing.
OVERVIEW OF OPERATION:
Installation will eliminate the often troublesome three brush regulating
system and mechanical cutout relay. It will be replaced with a solid state
current and voltage regulator permanently mounted inside an aluminum housing
that looks like the original cutout cover. Installed properly, this regulator
will allow complete and accurate current and voltage regulation of the
generator, thereby maintaining proper battery charge at all times. Maximum
output voltage will be limited to approximately 7.25 volts. Current output
will range from approximately .75 amps, up to the maximum allowed by the
generator, approximately 15 amps.
PROPER INSTALLATION WILL REQUIRE THE FOLLOWING:
A properly functioning Autolite model GAS generator configured for
Negative Ground Operation Only.
Elimination of the third brush inside the generator, converting it to a
two brush system.
Insertion of a small, hidden control wire from the regulator into the
* 6 volts DC nominal, 7.25 volts maximum output
15 amps continuous, 20 amps max, intermittent use
Negative system ground
Positive field winding control
This regulator has undergone extensive testing
over the last 4 years. Numerous units have been in service on Indian Chiefs
and Scouts which have performed perfectly, with no generator, regulator or
battery failures reported. Although no long term field tests have been
performed on the battery ignition Indian 4 cylinder, it is the ideal
application for this regulator. This is because the 4 cylinder battery model
generator turns at engine speed, which limits adequate generator power output
to high engine RPM conditions (3000 RPM and above). By controlling field
voltage the regulator will allow maximum generator output at much lower engine
RPM ranges (14 amps at approximately 1800 RPM was obtained during prolonged
U.S. $250.00 each (plus shipping) and includes the following:
