Short, draining the battery

replace ignition switch.

Most likely you've got something draining the battery. Read this post

Sounds as if you have a short draining the battery overnight. Take the battery negative off and run a 12volt test light between the terminal and the ground post on the battery. leave the key out of the ignition switch. see if there is a dim or bright light glowing in the test light. If either one is the case start pulling out your fuses and watching the light until the light goes out. When it goes out y have identified the circuit your short is in. ( headlamps, door switches, ect. ) Make sure to put each fuse back in the proper place so as not to burn anything up!!!!. By the way , you did NOT keep the positive battery terminal off to see if the alternator was charging did you? If you did you just burned up your new alternator,which by the way will give your battery a direct short to ground through the diode trio in the alternator, thus causing the battery to very quickly drain. and Why should you have to jump start a NEW battery? Check to see if you are lucky enough to have a charging fuse, if you did the positive off while running thing that fuse could save you if you have it.

Check battery cables are correct ! Prime suspect here ! Alternator may be damaged and shorting .. Don't drive any car that will melt jumper cables ! Something very basic wrong here.

Hi, I think you have a bad altinator or eletrical short which drains your battery over night, once you jump start your vehicle the altinator charges your battery enough that it starts all day but if it is parked for longer time the battery drains.

Check to make sure all courtesy lights are shutting off, under hood, trunk, dome/map lights, etc. Batt. could be shorted out internally.

No, this sounds like a weak battery. Check and clean if needed the battery connections. Take the car to a local parts store and ask them to check the battery.

there are not a lot of computers that could be causing the drain, so baring any aftermarket accessories you should start searching for an indirect short to power

prop hood and leave the doors open... this is important because you do not want to wake the computers once you start your test

next, unplug the negative battery cable and insert a DVOM in series

drain should be less than 80mA after 30-90 minutes

if drain is higher, start pulling fuses until the drain is isolated

It doesn't have a short. Shorts blow fuses. It has high parasitic drain. On a cad it might be hard to find but not impossible. Do you own an ammeter?

If the battery is charging and holding a charge all day then you could have a short some where that is draining the battery overnight.
