When is the last time that you had it on a shore power charger? I suspect if you were just using alternator and solar as your major charge sources you have left the battery undercharged and suffering from PSOC.
The BlueSky 2000e is a two stage charger, so it won't even be be able to tell if it has completed charge by going into float. Not sure what you have the Bluesky programmed for, butting 14.2 could just be the voltage it is set for. That is in no way a indication that the unit is fully charged.
My assumption that you are now seeing 13.2, could mean you haven't even made to the second stage of charging. ( That is a 30,000 ft level assessment). I would also check whatever you are running for a isolator/separator, is the alternator charge getting to the house.
