Well now the mech tells her that he has poked around and it has
confounded him. He found that the glow plug relay stays on for some
period after the car starts, which he somehow thinks is causing the
battery to run down. Some mention was made of a red wire coming from a
box going to short, but I am not sure which red wire or box. The girl
was going to find out, and take the car to the Benz shop next door.
It is clear the guy is not familiar with the car, guess I can't blame
him. The GPR is fairly new as are the glow plugs, so I doubt if that is
the problem. And even if it does stay on awhile that would not drain
the battery, unless it is stuck even with the key off, somehow.
She says the light comes on, so that should be OK -- in any case I don't
think that would drain the battery.
I gotta get this other car sorted and get it up to her and get this one
back.

I don't know the year/model but these alternators have only two connections:
One or two heavy wires that go to the battery + terminal (maybe via the
starter or a junction block) and a smaller wire for the idiot light. In
some models the alternator needs a trickle of current through the idiot
light to get the alternator started. In other words, if the "charge" idiot
light doesn't come on with the key in run the alternator may not charge. So
I'd first insure that light comes on when the key is first turned to on or
glow (assuming a charged battery).
Going that, you probably need a real mechanic unless daughter unit fancies
herself to be one. By the way, almost any FLAPS will test the alternator in
or out of the car.

Kinda funny, there is one like 2 doors down from her new apartment. I might
send her there.
She had this guy do the alternator a coupla weeks ago before she moved so
that is why I told her to go back there. I'm thinking that might not have
been the actual problem, maybe a bad wire or connection or short or
something.

You need for her to find a real mechanic, this isn't rocket science, but
it's obviously out of the current "mechanic's" area of expertise.
Look for an independent Benz mechanic.
