BC Generators
Integral Controller #35981
An improved version of the Integral Control #35981 is being introduced with production units and being
made available through our parts department.
The improved controller has designed into its circuitry a ballast resistor circuit which previously was a
separate component in the DC charging circuit of the BC generator models.
The separate ballast resistor, along with its wiring harness, must be removed from the generator DC
charging circuit and discarded when the improved controller is used as a field replacement for earlier
model controllers.
NOTE: On early models with plug-in connections, remove negative ground connection harness from
both controller and rectifier to case ground and discard.
The illustration shows the improved Integral Controller with its four color coded electrical leads and their
connection points in the DC chareging circuit
