electrical problems
Ok I got a new battery for my car because a battery light kept coming on under hard acceleration. Im pretty sure thr alternator is also bad now because it is still doing the same thing. Now also it acts like its trying to go into limp mode when I accelerate around 4.5k just like it did when my maf was bad but I have no check engine light or anything. Could this be because of the alternator not charging my battery? The battery tested in the car at 25% when I started the car by at 73 percent when it was off by the time I drove it to AutoZone. Any help would be appreciated. Thanks in advanced

Typically, when you see the battery light illuminated on the dash, it means you alternator is not charging as well as it should be or there is some other issue affecting the system, such as a bad ground.
It is more than likely that your alternator gave up the ghost! In which case you should replace the alt. or at least remove it and have it tested.
Usually, once the alt. goes it will begin to drain the battery. Thereby, wasting the battery away. Since you have replaced the battery already, it might be a good idea to get the rest of the charging system checked.
Seeing as replacing the battery didn't solve the problem.
You can also check your alt. by removing the negative terminal on your battery while the car is running. If the car shuts off, your alt. is done. This is the old school way of doing things. These days, I have the proper equipment.
Also, make sure your belt and tensioner are in good working order. I've seen belts slip enough to cause what you are describing, but only on heavy duty trucks, like 18 wheelers. Not cars though, good luck.

finally figured it out. it was the inline fuse, after my deployment I decided to look through the wire harness and found the (what I thought was just a junction block) with a fuse in it. so no more electrical problem, also if your interested you can buy a inline fuse from napa, its a 100 cost like 5 bucks or something like that.
