Does your car have OEM style battery cables with either no exposed copper or a nice solid crimp at the terminal end (common on imports and newer domestics)? When the vehicle "clicks" when trying to start is it a single click or a rapid series of clicks? A rapid series of clicks would still indicate a low voltage condition in the system.

The car wont start at all now. Not even by jumping it. The battery reads 11.6 and the alternator and starter tested the same. There is barely enough juice in the system for the dash lights to come on and they are extremely dim and th horn sounds dead too. Why can't I jump it now? Is there a relay or switch I can test or is 11.6 too low? Would this be from the battery? If the terminals were corroded would the alternator and starter still read the same as the battery but still fail to start?
