Electrical problem
2003 Ford Expedition V8 Four Wheel Drive Automatic

a month ago i put in a new battery because i woke up one morning a the truck was dead, assuming this was the problem.
Now it has happened again. if i charge the battery it will start but when i turn it off it will discharge again.
So i dissconnected the neg cable and charged it again and checked the volts it remained at 12.8 over nite. I connected the neg cable and the truck started. What kind of problem should I look for?

You have a short circuit within the electrical system -do the battery drain test below
