Hi Bob, 

I have your book but am looking for proper use of a rheostat to dim the annuciators on a KLN 90-B.  I have ground plus the annunciator light wires.  I am having a brain dump on this one.  Any suggestions?? 

Thanks,  Mark   [quote][b]

   A simple series rheostat may not be what you want. Do

   you know if the lighting is incandescent lamps or LEDs?

   How much current does the lighting input draw?  The pinout

   data I have for the KLN90 reads like there are two 14v

   lamp strings that are hooked in series for 28v and parallel

   for 14v systems. A voltage regulating dimmer like

    will always work.



    A rheostat's resistance and wattage needs to be sized to

    the total load while the voltage regulating dimmer's control

    functionality is relatively independent of total load and

    needs only sizing for total load. Is the KLN90 the ONLY circuit

    you plan to tie onto your dimmer control?
