What question are you referring to? Plain and simple, if the alternator fails and stops charging, then the battery will slowly drain not allowing you to start the car requiring alternator replacement and a battery charge or replacement. Pretty much any car can experience this not just a 2006 Ford Mustang.


http://www.autopartscheaper.com/SearchResults.asp?Search=mustang+smart Common Symptoms of a bad SJB. (this is a broad range of symptoms, your vehicle may only experience one or more symptoms at a time). • One or More Brake lights is stuck on at all time. • Battery Drains Quickly When Car Sits for a few days • Headlights are on bright all the time. • Turn Signals or parking lights are stuck. • Power Windows do not work • Instrument cluster malfunctions • Dash lights quit working. The original Smart Junction Box installed in these Mustangs had 2 major problems. Problem 1: The windshield leak problem. These cars had a bad seal from the factory that allowed rain to drip down on the bottom of the windshield. The water leaks directly into the SJB box, and ruins it. Problem 2: Poorly engineered part when the car was new. These circuit boards were poorly

Gary, as to my knowledge, NO, Ford has done nothing about this. I have a '06 GT and it won't keep the battery charged. When going to start it, it seems to hesitate. I have cleaned the terminals, replaced the battery, alternator and starter and still the same damn thing. It was recommended to me in another related question in here to install a grounding wire (strap) between the negative post of the battery and on a mounting bolt of the alternator, which I did and still the same thing persists. So, we are all the in same boat as it comes to this problem with 05-07 Mustangs and draining power. Good luck.
