recently bought a 06 night runner and ive had no problems with it for a little over a month now. this morning i went out and pushed engine start and nothing. no crank, nothing. not even a click. volt gauge is at 12 volts, and i tried adding jumpers to a smaller batter i have for my vette but i dont know if that battery has any juice left in it. needless to say it didnt work either. volt gauge also remained at 12. not sure if this 10 cylinder needs more than 12 to start as ive started my sbc's on 12 and been fine. i live in FL so i dont think cca's is a problem, bought the truck about 60 miles from where i live. im not a dodge guy and new to this platform/motor so any of you gurus out there that have seen this before could chime in id appreciate it. my first thoughts are getting the batter tested, and no i dont have a code reader.
