2000 Chevy Blazer...battery light staying on

2000 Chevy Blazer battey light came on today and won't go out. Charge
indicator is sitting at nogtch halfway between 9 and 14, roughly 11.5
and holding. Checked all fuses and relays and cleaned corrosion of
positive post. Cables appear good otherwise and disconnecting battery
after starting, engine runs fine. it doesn't "appear" to be the
alternator. Anyone have any ideas?

You proved absolutely nothing disconnecting the battery while it the
engine was running. 9 volts will keep it running, it takes 13.5 to run
everything and keep the battery charged. I've posted constantly
do not disconnect batteries while modern cars are running. Do a quick
Google for "disconnect battery while engine running". That method went
out when computers started showing up on cars., and even on classics
it still doesn't tell you anything, other than it is putting out just enough
to run
the engine.

It probably is the alternator. Take it to autozone and they'll check it for
free.
