Car: 1994 Sentra LE

Ok so my battery light and brake light came on......I took the alternator off and had it checked. Sure enough that was the problem... I picked up a new alternator and changed it out...
-Drove around for about a day and a half, next thing you know the lights come on again... So I take the battery out and have that checked... turns out that was bad.
Replace the battery and the problem was gone (until this morning)
Both lights come on again...and by the time I park at work everything on the car is dim.
What is wierd is that when I jump it the car starts up like nothing and is good for that day then the lights on the gauge cluster turn on again.....and sometimes when I hit the brakes the radio turns off
Any suggestions on what's going on with the car or why this problem is occuring ????

Check the brake light switch first, it might stuck in ON position or it shorted to the ground and drains your battery during a day.

Check charging circuit start out at the alternator ground and to the battery, check for parasitic drain when the car is OFF.

Everyone must have a multimeter and use it, use it, use it.

Exactly ... Check for something that is getting power with the car off.

Ok cool....i'll be sure to do that...
One more ???
I noticed if I leave the car sitting for about a day or so....after it has turned off on me, It will start up just fine....
Any idea why that would happen?? It seems a little wierd to me...
