Hi there,
Thank you for the donation.
What you need to do is have a current draw test done, this is done by placing an Amp meter between Battery Pos (+) and the battery lead, with the key out and doors closed check the current draw, there should be only around .15-.2 amps max, any more and you have a circuit open, start pulling fuses and circuit breakers, and fusible links one at a time to isolate the faulty circuit, also unplug the alternator as a faulty diode will cause this and still show a charge rate, if in doubt get your mechanic to do this test for you.
