I have tried to tune the knobs labeled as Pipper light control, Scale back lights control, and Fix net light control. I cannot get my ASP to do anything, or respond to any input from the knobs even when it is powered.   
However if I do an instant action mission that already has the gun sight powered and lit, it performs perfectly.   
Issue fixed, My problem was that I had the emergency inverter on and had adopted this into my start up procedure.
