Question Automotive/Loss of voltage

I own a 1987 Chevy Caprice Classic. For the past couple of weeks I noticed the car losing voltage. The car idles lower than normal;the indicators blink slower than usual;when the headlights are on it gets worse.The horn is blowing weak as well.
I replaced the alternator and the battery.The problem still exists!
Please help if there's another way to beat this Thanks

Do the output test I have outlined in my post "The Basics" below and see what you get.

Just because you put in a rebuilt alternator doesn't mean it's god. Some parts store rebuilts are junk out of the box. Stick with an AC Delco rebuilt.

How old is the battery?
