toddalin: first thank you very much for taking the time to do this, and timed relay release operation is exactly what I am looking for. My only concern is you mention with C3 at 1F will give the relay 3 minutes of open. That is much too long as the board shuts down at 75 seconds and the Sierra stutters at the next start up.. Can P1 be adjusted down to about 60 seconds? or do other changes need to be made to accomplish that? Much appreciated.
