Why does a 1997 dodge intripid drain the battery and wont run off the alternator I also replaced the alternator and the battery?

Most Chrysler products will not run with the battery disconnected, This is not a sign that the alternator does not work nessisarly. disconnect the battery and leave it, see if the battery itself has an internal short, allso disconnect the alternator plug and wire and leave it sit, do one of these at a time and see if you can isolate the drain, could be a stuck relay or under hood light, glove box light or trunk light. Remove fuses one by one until you isolate the circut with the drain and go from there.
