Thanks for re-posting the schematic, as it confirms my understanding of what you meant about the positive lead of the buzzer/LED.
As with the Low Battery warning suggestion, yeah I could make use of that second half, but I already have a (2-phase) voltage monitor implemented into my design that even disconnects the load as soon as it drops to a certain voltage range
Signing off now Eric, thanks once again, and I will let you know how it went as soon as I can test it out.
