This is not a key-off drain. However, if the alternator is shot, the car won't keep running either. Eventually the reserve power of the battery will be gone and the car will die.
There is a charging system fault somewhere. What parts are there? Alternator, regulator and battery. Anyone think of anything else in the "circuit" that could be failing?
Is the voltage regulator integrated into the alternator on this one? I'd be tempted to replace both, but I'm loathe to throw parts at a problem without having the proper diagnosis.
And to the mileage and driving the car, I meant once this problem is sorted out, you should drive the car more...
