i just bought this car used and noticed the battery was dieing overnight. so i replaced the battery and overnight it died again. i tested the alternator and its not that...i also noticed that the radio would cut in and out when i drove it..thnk

Something is stuck on, like trunk light, glove box light. Door not closing all the way and dome light stays on, etc...

** If a wire were touching ground (that's what a short is), the fuse would blow and that circuit would stop working. It's not that. **

i don't think a trunk light, or any other small light will drain a new battery that quick..... it must be s short or something that steals a lot more power like headlights (they will take a couple hours even on a new battery)

... watch it at night, even though it does sound like a interior light, but most likely is a short .... that will be a PITA to find tooo...
