I have a 2005 mustang gt recently the battery started draining with a few caveats
-after 2 hours car will not start
-lights still work
-electronic door still works
-radio and ac still works
-just had it sit idle for 4 days and same thing won't turn over just clicks lights and all accessories still work
-when I jump it it doesn't need to charge: the moment I hook up the cables it starts.
-if I turn it off after running for a while it starts right up
-any idea what this is?
