My Ford Expedition Eddie Bower 4wd drains my battery every day once its jumped off its fine all day, Battery,Alternator, Starter are all good any ideas what may be wrong with it

It's a parasitic drain on the battery, and can come from any number of electronic components. Google how to tackle a parasitic drain, or watch some Youtube vids. Most methods will involve a meter set to amps, you'll have to monitor the current draw on the battery with the vehicle off and see if it is a specific range. If it is excessive, then you'll have to start eliminating systems by pulling fuses or relays until the draw drops back into it's acceptable range. One catch is that constantly opening a door will keep some computer modules in an active state, so either disable the door ajar switch (not easy it's buried inside the door), pull a fuse that governs the door ajar switch, or leave door closed for 10 minutes to allow computer to go back to sleep before measuring draw on battery (have someone stay inside vehicle with door shut and pull fuses in that case). It can take some time so have patience looking for the draw. Also visually inspect every part of the wire harness for shorts, abrasions, burned wiring, etc. Some components, like a rear wiper motor or controls, are subject to a lot of moisture and are prime suspects in a parasitic draw. Usually a draw that can kill a battery in hours or overnight is more than a simple bulb remaining on (that type of draw would take days before finally killing a battery). One that can do it overnight might be a small motor, or a stuck relay or module. I had one where it was a bad IAC motor (intake air control), part of the throttle body. Took forever to isolate. A final word though, before investing a lot of time checking minor components, eliminate the major one - get a thorough LOAD test on the battery, alternator, and starter. Test starter relay, plenty of guides online. A battery can pass some voltage tests even with a bad cell, so get it tested under load. Good luck.
