I drove my sorento yesterday to go camping. Approximately 60 miles from home. Turn vehicle off and went into camp store to look at map for available sites and wait on family to arrive. Roughly an hour later tried to start car and it just clicked a few times. So I tried again and it did the same thing. I had no lights either. So I tried to jump it and it just clicked and the hot post sparked . Even then no lights. So today after it sat all night I tried to start it again and it still just clicks but my lights are back again. So I checked the battery with a volt meter and have 12.68 volts. With the lights on I have 11.99 volts. While trying to start it it has 12.56 volts as its clicking. So I pulled the battery and tried to jump the car straight to the cables and it still just clicks. So I don't think its the battery since I eliminated it from the car. Any help would be great as I don't want to pay a tow bill from 60 miles from home.
