Battery guestion for a guru or two
I hope this question finds an expert. My unit is a 2009 Jayco Eagle TT. It came with a new deep cycle battery. When on shore power and I assume the battery at full charge, I read 14.4vdc at the batter...

Your "new" battery is pretty discharged. 12.2 volts with little load is about 60% of charge (and you shouldn't go below 50% charged or about 12.1 volts). Also since your converter when powered is running at 14.4volts it sounds like it is trying to charge the battery as 14.4volts is boost voltage.
Assuming there is nothing really wrong do the simple things first:
- check the water in the battery to ensure it is just over the plates
- plug into shore power and let the converter charge the battery for at least 24 hours. Around 3 hours or so you should see converter voltage&battery voltage drop down to the 13.6 range
- After the 24 hour charge unplug and unhook the battery, let it sit for 24 hours. Measure voltage, should be 12.6+
If all of that works as described then your problem was only a pretty discharged battery.
