Mystery electrical problem with my 2006 TJ

HELP!!!!! I have an electrical issue with my 2006 TJ. I have to rely on my fellow forum jeepsters to help me out since two different auto services could not find a problem including Safford Jeep of Winchester, VA. The issue is that sometimes the Jeep can sit for a month and start right up. At other times, the battery (new by the way) can be drained overnight. I am told there are not electrical issues with the Jeep. I am thinking it could be something in the switch when I release the key from it. Has anyone had this kind of problem? It is becoming very irrating and if not, should I put a battery bypass on the Jeep? Help me all you Jeep brainiacs out there. Many thanks...............

So the jeep had the same problem before the new battery was installed?......or did it start afterwards?

you need to list all after market electrical stuff you installed first to get some real help, so if you installed a new stereo fogs, winch, list all that stuff first. Then I would check each accessory for a draw to begin with.

I highly doubt its the ignition switch. If so disconnect it, the plug is on the left side of the steering wheel behind the upper and lower steering wheel plastic covers. Unscrew the 3? screws under the bottom cover, then remove both covers. Squeeze the ends of the large white connector going into the igntion switch and pull down, it should come out easy. Install a cheap push start from autzone for a while and see if the problem goes away.

Make sure your battery cables are ok ive heard stories of them internally corroding and causing a draw.

Either something is left on/always on (large draw) or you may have an intermittent short. Does anything ever stop working when you are driving??

If you have a multi meter that could read current and are comfortable using it. Set the multimeter to read current. With no key in the ignition. Remove the negative battery terminal. Place the meter between the negative terminal and the negative wire lead. You should be reading less than 50 ma. If you read higher you could start pulling fuses and look for a large jump down in current. This will lead to what circuit has the issue. I would start with any add on circuits.

I am going to add in the possibility that the alternator has a bad diode or is being full fielded by a faulty voltage regulator.

Now that you mention it, I've experienced that on my 05, too. After 165k on it, the key no longer really "locks" in there. I can pull the key out when it's running...Therefore, being careful to turn it all the way off prior to removing the key has become critical. The day may come when you and/or I need to swap out the cylinder, but for now I'll live with it.
