Did you do any testing before you replaced anything? You can use a digital multimeter to do some testing, battery and generator. Where I live some of the national brand auto stores will test these systems for you. If there is a problem with wiring circuits for generator or battery, new parts won't fix it. Another thought, maybe too much amp draw with the key off, something draining your battery? You would have to check amp draw. If too much, pull/replace fuses, one at a time. When you pull the fuse on the faulty circuit, the drain returns to normal. I use 50 ma as a generic spec. Some vehicles may use a little less, some may use a little more.
