94 buick regal custom battery problem
I have this 94 buick regal custom 3.8. The battery is totally dead after sitting in packing through the weekend. It happened last weekend. I had it jumped and drove the whole week daily to and from work without problem. It is dead this weekend again and I checked everything, lights, radio, to make sure they are off. What could be the problem? The car has about 137K miles on it. Thanks.
