Sounds like a bad diode in the alternator. Try this: get a test light and unhook a battery cable, put the test in- between the cable end and battery post, if the light turns on then you have a draw large enough to kill an battery overnight, next electrically disconnect the alternator, if the light goes out then there is your problem. If the light does not go out then you will have to start pulling the fuses one at a time noting the location until the light goes out, when it does find out what components are on that circuit and repair or replace as needed, then start putting the fuses back in and reconnect the alternator.
