Here is how to detect a drain in system! Use a test light, Hook up test light to the negative terminal on battery. ( unhook terminal first.) connect opposite end of test light to negative on battery. If a drain, light will be on. Start pulling fuses from fuse box. when the test light goes out, that is the problem curcuit. let sit 3to5 minutes before pulling fuses. Good-Day!
Myguess is that you have an electrical short which is causing a drain on the battery. The way to check this is to get a 12 v test light. Unhook the negative side of the battery. Hook the test light up between the negative battery post and the battery cable. If the light comes on, You have a short/drain. To find where the short is, you leave the test light hooked up. Then you start pulling fuses until the light goes out. However, your car stereo needs to be completely unhooked before you do this test because most stereos have a constant electrical source so that the clock stays accurate and the memory stays active so your programed stations don't get lost.

Something is draining your battery overnight and once you start running it, it recharges your battery. If you have anything plugged into your cigarette lighter, unplug them. Unplug anything that you can, like if you have an amplifier for your stereo or anything else. Tonight unhook your negative terminal, and then hook it up in the morning and if it is ok, then you know that is definitely your problem.

For safety purposes always always remove the negative side first. This eliminates the possibility of shorting out your wrench against the body or any other negative charged part. There is strong possibility of shorting out the battery which could blow up. This happened to my brother as a kid and he ended up with battery acid in his eyes.
Try unhooking the negative side of the battery as this may reset any relays.
Re-check battery terminal and make syre they are tight and making good contact, check for corrosion and remover all if ther is any. Check main battery fuse and make sure it good. Check battery cables and ground wires. Good Luck
you could be draining the alternator and battery with the new stereo..depending on how you hooked it up you might try charging the battery back up.you were supposed to take off the pos cable not the negative
