My 06 3500 cummins wont start after I pulled the battery off while running to use on my tractor. It stalled when I put the truck in gear to move it while the battery was still on the tractor and also a small round red warning light is flashing just to the left side of the temperature gauge. Did it set off some kind anti theft system so the truck wont start now? Also what to do to fix it, does it need to go to dodge house or a mechanic thats got the newer diagnostics machines. Thanks
