This solid state voltage regulator is
designed specifically to fit high output three brush GDE model Autolite
generators using a 6 volt negative ground system and external TC model
regulators. This generator and regulator combination was standard equipment on
all Indian motorcycles from 1948 through 1953 and available as an
option from 1938 through 1947.
CONSTRUCTION: The solid state regulating
components are permanently mounted inside a powder coated aluminum housing
which is CNC milled to look exactly like the original stamped cover. The
housing also acts as a heat sink for the internal components. The riveted ID
tag is stamped with the correct model and year of manufacture to fit your
specific machine. This housing is mounted on a cadmium plated reproduction of
the original base. Units can be supplied in either single or double terminal
configurations depending on your application. The end result is a reliable,
maintenance free, modern electronic regulating system housed in an exact
replica of the original TC style regulator.
OVERVIEW OF OPERATION:
Installation will eliminate the often troublesome three brush regulating
system and the mechanical cutout relay and regulator. It will be replaced with
a solid state current and voltage regulator permanently mounted inside the
unit. The solid state 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 vary automatically, based on demand, from
approximately .75 amps up to the maximum allowed by the generator,
approximately 20 amps.
PROPER OPERATION WILL REQUIRE THE FOLLOWING:
A properly functioning Autolite model GDE generator configured for
Negative Ground Operation Only
Elimination of the third brush inside the generator, converting it to a
two brush system.
* 6 volts DC nominal, 7.25 volts maximum output
20 amps continuous, 25 amps max, intermittent use
Negative field winding control
This regulator has undergone extensive bench
and field testing over the last 4 years. Prototype units have been in service
on Indian Chiefs and 4cylinder machines with excellent results reported. The
battery ignition Indian 4 cylinder is the ideal application for this
regulator. The battery ignition 4 cylinder generator turns only 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 (15 amps
at approximately 1800 RPM was obtained during prolonged bench tests)
