My new battery keeps dieing over night its new and the alternater is new I checked all the grounds and I can't find any thing that is staying on in the car

Need parasitic load test... Google it... This is not a DIY fix.. You will just get more confused!!.. There is a video on YouTube, watch it then you decide...

you might want to take a test light, disconnect the positive side of the battery and connect one end of the test light to the battery positive side and the other to the wire of the battery. If the test light start glowing then you have a short. I would first disconnect the starter and see if the short stays on. if that does not solve it then test light connected one ends the battery the other end of a wire start pulling out 1 fuse at a time to see when the glowing stops. when the glowing stops, there is your short. you will have to repair that then you should be ok
