For the past year I haven't been driving my 240(second vehicle) that often since I am traveling alot and I leave my car at my company's parking deck for weeks at a time. The good thing is that I live 2 miles from work and it is very easy for me to get to the car.

The first time I started to experience problems was in January when the old battery would get very weak during cold weather. I went ahead and I decided to replace my 5 year old battery with a new Champion. Everything seemed to be fine for 2-3 weeks. Since I was driving the car for only 4 miles a day total I decided to get a Vector battery charger and I recharged the battery in 5 hours. I installed the battery in the car 2 weeks ago I today when I went to check on the car the battery was completely empty. Right now I am recharging the battery for a second time using the Vector charger. I do not believe this is a battery problem since I had the battery sitting a home for 4 weeks and the charge was kept fine.

My question is the following. What ghost load could be causing the battery to drain completely slowly over a period of 2 weeks?

The only strange behavior I found was that the power locks would work intermitently?

Could this be a relay problem like the power lock relay getting stuck?

Any thoughts or recommendations on this problem?

Thanks

Mike
