Hello,tried to post a little while back and it didn't go through,or I can't find it. Anyway,recently bought a used 2006 300(260 e11 on top of air box,not sure what that means unless the airbox fits both). Story goes it has no spark. My daughter and I are done cleaning the fuel system and moving on to the electrical side. Have found some broken manuals,never the full 2006 one. To start this off right,could someone please tell me the correct battery? I have found in a manual 5ahr,but if I get a 12ahr,will I start to blow fuses and starters? Also,can i do the troubleshooting with a batter jump pack hooked straight to it so as not to run a new battery down? Thankyou!
