Your alternator is dead.

I am 100% sure that's the problem.

I 100% agree with White93ltz your alternator is a goner, no doubt about it, your previous battery may have still been good.

Low voltage reading (or Red Volt, Gen MIL lamp indicates that the alternator is not putting out a charge for the electrical system.

The reason you were able to drive another 3 days on a new battery is that the battery had a full charge to start with and ran down by the driving since the alternator was dead.

I also own a 1994 Caprice. When I first bought the car was having the same problem. First off I figured replace the battery. That wasn't it, next in line check or replace the alternator. That wasn't the problem either. Even went as far as replacing the starter. To make a long story short. Had a buddy lock at the carfor me. The problem was in the wires. They wasn't carrying enough amps. Something easy to check.
