I was actually going to ask the same question. The other night, my buddie was leaving work and had to catch a ride home. He has an 05 (or 06) with the 5.9 in it. The batteries had power because it would have the lights on. Then, he tried to start it an it would just click. Like the engine was locked up or it had a bad starter. I checked the connections I could get to, but no dice. It was about 0-2* outside and it had been sittin that way for at least 10 hours.
