87 Honda accord...water in battery>boiling

Measure the voltage at the battery as you rev the engine up to a few thousand RPM. If it ever goes above 15.1 Volts, it means your voltage regulator (inside the alternator) is broken, not all that uncommon on rebuilt alternators. I'd wear protective gear while doing the measurement, battery acid in your face is the last thing you want.

BIG question: Was this an AUTOZONE alternator?

autozone is the worst for alternators. also try to get a mitsubishi one as opposed to a nippon denso one if you can. i think theyre better built.

Many are those who have learned the hard way that OEM alternators and starters are the only dependable ones, especially for Hondas. There just aren't any good rebuilt brands out there. As hondaman and TeGGeR warn, Autozone is hopeless. And the situation you describe - new alternator and new battery, but battery still boiling - must be the new alternator running wild (the internal regulator is fubar). I can't think of anything else to account for it.

Will change the alternator. Hopefully will work right??????

That's a good bet (kind of a Magic 8-ball response there, but the point is that there are no guarantees.)
