    No, the 7805 is good for 1A of current, the 78L05 is good for 100mA of current. This is not the reason.

    Did you give it enough time to charge up all the caps?

    Have you looked through the timing diagrams?

    Does the kill switch work? or work after time to kill has passed?

    The relay is suppose to come on when you first power the device on. This is how the design works.


    Leave it on for 10 minutes, if it hasn't turned off, then start whining.
