I am trying to install an external indicator light on the outside wall of a pump house. The submersible pump controller is a frequency modulated Franklin Electric Subdrive 100. The output voltage and frequency vary greatly with pump demand. The pressure switch output appears to output milliamperes and is connected to a printed circuit board. I have called several local pump companies without success. Does anyone know how to connect subject light?
