raddad, If you can drive your Crossfire to an auto parts store they can check your charging system and battery. Also, the store can hock up a scan tool and search for any Diagnostic Trouble Codes (DTC) for free. That would be a good place to start.

Also look around this forum for help on all things Crossfire. Start by going to the section TSBs and How-To- Articles for a wealth of information. Particularly there you will find "Pizza tech help pages", where you will find instructions as to finding battery drain problems AND "Index of Crossfire problems and repairs."
