Im completely lost on this thing. About a year ago the alternator went out, so i replaced it with a reman from autozone. Worked great for awhile. About a month ago the battery went out, so i went to bennet auto and got a new ac delco battery. 2 days after that the battery is dead again. I put a volt meter on it and its showing 12.3 volts. When i turn on all accessories (AC, radio, headlights) it dropped to 11.7 volts. Thats why the battery is dieing. SO i exchange the alternator on another reman, and its doing the same thing. All connections and fuses have been checked and are tight. Anyone have any ideas?

What is the voltage with the truck running? It should be about 14 volts if the alternator is good.

wiggle your ground cable as low as you can grab it while you have the tester on it see what happens.

make sure all your connections are clean.

I'd start with ground wire and clean the connection.
