my aux reads about 13.5 charging at idle and about 14.0 to 14.3 when
running down the road depending on RPM.  after an overnight rest it
reads 12.1 to 12.3.  there are some low drain items attached to it.

my main start battery reads 12.3 to 12.4 after an overnight and only
has the clock running on it.
charge voltage at it reads just below the charge voltage to the aux
battery.  (i have both lines independantly gauged.  i use six gauge
line to my aux battery bank connection.

when i have all three aux batteries on the charge line i get about .2
volt less on the aux gauge when charging until all batteries are full
charged.
