Did you check the wiring circuits for battery and generator? If something wrong with wiring circuit, somewhere, replacing the parts won't fix it. Can you use a digital multimeter and do some testing on your charging system and battery. Everything off, place meter leads across battery posts, the generic spec for a full charge is around 12.6 volts. Then with engine running, take that reading again, if the charging system is working, the second reading should be higher than the first. You can do same thing at generator bat terminal. You could have too much drain with everything off, make sure no lights left on anywhere, best time to check is in the dark. If too much drain, pull/replace fuses one at a time, when you pull the fuse on the problem circuit, the drain returns to normal. Then you check everything on that fuse circuit.
