troubleshooting

 Hello All,

    I have a problem, when my car is turned off my battery drains it will start if it only sits for a couple hours but it is noticable that the battery is not fully charged. If the car sits over night however it needs to be jump started. I've already checked all the basics and have also disconnected the battery overnight to see if the battery just wasn't retaining a charge. It started fine the next morning;So the battery holds a charge. I thought I had the issue narrowed down to the stereo/cig lighter because when I removed the corresponding fuse then let the car sit overnight  the car started fine the next morning but since then it has not started when removing the fuse and having the car sit overnight. So do you guys have any tips on how to figure out where current is being drewn from? Any help would be greatly appriciated.

try charging the batt to fully charged...disconnect the alt from the battery...then reconnect the battery.then reconnect the alt. if it still does that..time for a alt..or that cig thing is staying on..but that still wouldnt drain the battery that much..
