1992 Isuzu Trooper 6 cyl Four Wheel Drive Automatic 145, 00 miles

I just had the alternator rebuilt, I installed it, it still did not charge the system, removed alternator again, and took it to auto-Zone, where it checked as working, and was putting out 14.6 volts.I installed it again, system still not charging. Took the alternator back out, and had it tested at NAPA. The alternator and voltage regulator working 14.7 volts they specified voltage regulator was also working. Could there be a relay that could cause this. When I remove batter terminal, engine dies.
