1991 Chevy Corsica, 3.1L V6 engine, approx. 145000 miles.
Ok so I was having a problem with my battery going dead so I had both
the alternator and battery checked, as I know that having one which is
bad can cause the other to go bad as well.
It turned out that indeed both the alternator and the battery were
bad. I replaced both ensuring that all batter and alternator
connection were clean and free of corosion. I also check all ground
connections to make sure they were good as well. The serpentine belt
is nice and snug and appears to still be free of cracks and over wear.
My problem is that I am still having a problem with the alternator not
properly charging the battery. With the engine running, I unhooked the
negetive battery cable (yes I know its not necessarily a good idea,

What else is there that I should check that could be causing this
problem? I know the voltage regulator is built into the alternator so
that isnt a problem but after that, I really have no clue where to
thanks for any advice and help
