Here's the circuit as it stands. I'm still working on debugging it. RadioRon, would you please take a look at it and see if it matches the simple logic diagram that you posted to assist me on this circuit? It doesn't seem to be acting like its supposed to. It seems the output of the 2 ICs on my main portion matches the voltage of type of chip I'm using.I'm also getting some lower voltages from the transistors which is not desired. I need the voltage to be high enough to power the Warning LED, but as it is, the voltage is possibly too low to run it. It works fine when the Refill LED is illuminated. Otherwise, the 555 portion of circuit on the right hand side is fine. I need help getting the main part of the circuit straightened out. The attached picture shows what I mean by low voltages going to the warning LED and the 555 portion of the circuit.
