Battery issues.

Ok two days ago my battery light came on, later that night while driving everything dimmed and luckily I was pulling into my parking lot. So i got a jumped from a jump box and as he removed the jump box battery died instantly. Sigh, so I removed the alternator and had it tested and it came back good. So then I had the battery tested and it wouldn't read so we replaced that under warranty.

So fast forward to today, running some tests and I saw that the voltage read 11.9 which is bad because I'm sure it's supposed to be at 13.9ish. Long behold the battery light came back on. Wtf is going on? Do I have a draw somewhere? Any places to start at?

test the power at the battery, car running, it should be 13 volts or higher.

if the battery's new id think the alt is going bad.
 
Check all of the connections at the alternator, and the wire going to the battery. It seems intermittent, even with a new battery and a good tested alternator. If that checks out the alternator may have intermittent problems.
 
Thinking it's the alternator. Battery is back at
13.5. All of a sudden.

Go to auto zone and get the alternator and battery checked. they checked mine once and they were right on. I did a check on my battery while the car was running one time and I was getting 14.2 Volts so pretty much that eliminated the alternator.
