Not sure If I drained it all the way out, but I left my ingnition in the "on" position last weekend, I was trying to roll up the rear window before I went on our trip. My key can just be pulled out in any position, so I must have left it in that position when I pulled the key out. Anyway I got home and it was dead, charged it up and got a jump and it fired up, even drove it around for a day, however It sat there for a couple of days after, now it is dead again. I am afraid that I have trashed it by letting it drain out. I just bought the F%$#ing thing. Do I have any options, I am sure the warrenty does not cover me being a dumb a$$. '84 K5 Chevy in my blood.
