My 2008 sorento has been running fine but yesterday I shut it off and returned 1 1/2 hours later to find that it will not start. It hardly even gives a click and all lights black out when trying to start. I am having trouble finding the location of the starter, I thought maybe tapping it will dislodge/help engage it. I have tested the battery and it seems fine. It is < 1yr old. I have tried using a booster pack and it still gives me the same problem. Please help. Diagrams?
