You lost me somewhere near "melt in frying pan", but is sounds like you
are having fun...

just an FYI - there is a diagnostic channel on the climate control that
reads out battery voltage on the red LED display.  It seems to be
accurate, but the actual point of measurement is not the best.  If you are
really concerned about battery voltage, you need to measure it at the
battery terminals.
