Was this voltage checked at the battery when the vehicle is running? 14.2 DCV is good voltage at the battery when the vehicle is running.

Ok, Just because it is a new battery, I would have it tested, it's not unheard of that it could be bad. Otherwise the charging system is working, so then it's to figure out what is draining the battery down if the battery is good. This is what would need to be done, check this sight out.... www.youtube.com/watch?v=QRso1A0VScw
