Are you prepared to do some tests on this yourself or are you just looking for some possible causes?
What he needs to do if he hasn't already is disconnect the negative battery terminal and place an ammeter in between the disconnected cable and battery post and get a reading of exactly how many amps the draw/drain is, with everything turned off. Then start pulling the fuses one at a time and leave them out until the draw/drain is lower than 50mA, then he would have a starting point of which fuse circuit to start checking.
That sounds like a loose battery cable connection to me.
you are welcome. Don't forget to rate me well, so I get credit, after all this is my job.
