Does the charge light come on with the engine stopped and the ignition
key turned to the on position without cranking the engine? If not,
the alternator is bad. Good luck. Al

You either have an alternator that is not recharging the battery
properly... or you have a constant current drain on the battery.
From your story... a new battery going dead overnight indicates to me
that you have a heavy constant drain on it. To check for this...
disconnect the positive battery terminal first. Recharge the battery
with an external charger. After the battery has recovered, insert an
ammeter in series between the positive batt terminal and the positive
batt post. You will most likely be able to find a small handheld
multimeter from a neighbor to be able to perform this test. Currents
in excess of about 100mA would be considered a problem. These currents
could be caused by... but are not limited to... a partially shorted
diode in the alternator... or a glove box or truck light that is not
shutting off.

I had a problem that was similar. The battery went dead and wouldn't
hold a charge. I could jump start it and the engine would run, but after
shutting the car off, it wouldn't start again. I brought the old battery
to Sears and got a new Diehard from Sears. Brought the battery home,
installed it and it wouldn't turn the starter over. I jump started it
and it ran until I turned it off, then dead again. I checked the new
battery with a tester and it was very low. Brought it back and they
confirmed it was dead. The second new battery worked, and is still
working some 5 years later.
