When I tried to start my truck yesterday evening, it acted like a dead battery. My buddy gave me a jump but it still wouldn't charge or anything. So I took the battery to Advance and they checked it. It was perfectly fine, it's not even 6 months old. When I put the battery back into the truck, everything worked fine. The radio came on, dash lights and headlights. But when I turned the key, the starter clicked once and then all the lights went out. I wiggled the negative cable again and all the lights came back on. I've done this whole thing multiple times with the same results. The starter clicks once and all the lights go out again. I've smacked the starter while my buddy turned the key and still get the same results. Right now it's stranded in a college parking lot. Anybody have any ideas? Thanks you in adavance.
