Probably a parasitic draw, why did you change the Alternator no output? was it bench tested or did you check it at the battery for 13.2-14.8volts..how long does it take to discharge the battery overnight or in minutes or hours? I suggest checking ALL grounds and connections AGAIN

shorted diodes in the alt and that took out the battery
