My house batteries ran a little low, unexpectedly a couple of months ago. I have noticed that my DC gauge on the engine instruments is reading at about 12.3V on the port side (house) and 13.8 on the starboard side. Would a faulty battery cause this? They are group 31 AGM batteries from Sears.
Or, do I need to pull the alternator and have it tested? It would be easier for me to swap out the house batteries with the bow thruster batteries. They are all the same.
