!2 volts is not charged and can see where you would have problems. You should get 12.7 v on a fully charged battery. How many amp charger do you have? By aux battery I assume you mean the battery that runs the 12 v system in you coach? How many amp battery charger do you have? It will take a while depending on the number of amps your battery charger is putting out to fully charge a battery that has been run down to 12 v. Start with a fully charged battery first, then take readings.
