Chonic Alternator Failure

have battery tested, check main battery wire at alternator for voltage, check ammeter in dash for failure
Had a nice sunny day today, carpe diem, so as I was leaving for work I popped the hood and placed my DCOM probes in the batter clamps, rested the hood down and set the meter on it.

After sitting all night, battery read 12.6 Volts
During cranking ~10.5 Volts
After start up ~15.4 Volts
At alternator battery stud 15.75 Volts

After work I picked up a jug of distilled water now that I know I need it. Also it appears this current alternator has dropped another feild and I'm down to one.

I think what I am going to do is go ahead and get in to AutoZone at my soonest convience and pull the alt and VR so they can go ahead and test them bad and replace them. I'll recheck these readings on the fresh parts and see what I get.

Tommorrow I'm gonna pop the caps before work and top off the battery which I'm now almost 99% has probably had the water boiling out of it for awhile now.:violent1:

Should I proceed with this gameplan guys^^^

Keep in mind, I have a lifetime warranty on the alt and I'm only several months into the 1 year warranty on the VR so they are free to replace.
