Ok guys tell me if this is possible ,have a 04 400 kfx batt has been great up till this week ,have it in garage and never keep key in it , all of a sudden go to start it and its dead ,put charger on it says full and it starts right up ,leave it for 3 days go to start it and its dead again ,?what could be draining it !!! have not called dealer yet because im not sure what to say to them ,any ideas ,should this be covered under warentty .thanks

 

it is most likely a poor connection somewhere... if its new enough, take it back to the dealer, if you can't do a quick visual inspection, finding a loose wire...
