I had a 2amp draw from my battery and the car would die over night. I took it to Ford and they found that two of the six factory amps were bad. Replaced the amps under warranty and problem solved.


Good Luck

Hey thanks for the tips and man are people that brutal on here all the time!

So being a contributor makes u an ***** and sarcastic! Thanks for the post but the radio was not the problem and it has since been solved. Can't a proud mustang owner give a little info even if it isn't relevant to the post?

Dude, people are normally nice. Some have a weird sense of humor, others don't...just like real life out there. You can ignore them and move on..that's what I do...reference your issue what exactly was the problem if not the radio...I am curious.

There are only two things that can discharge the battery when the vehicle is parked:

1) a drain by the vehicle i.e. a short somewhere, or a module which won't "go to sleep." If you use a meter to determine if there is a draw on the battery from the vehicle, it can take up to 30 minutes or so for every module to shut down. After 30 minutes, the battery draw should be about 0.1A.

2) a drain caused by an internal problem with the battery. When you have the battery load tested, it may test out OK, because they only test the battery fully charged, and presumably, reasonably soon after recharging. If there is a small short inside the battery, the battery may test out OK under load, and then be dead in 2 days.

Also important is that the capacity of the battery will be greatly diminished after repeatedly being discharged to the point where the vehicle will not start, meaning in the future, it will go dead much sooner then when new.

Since the winter started I noticed my 2007 GT tends to not start after 2 days. I took it to the dealer and they said the battery tested OK and that the ECU in "these new cars" draws more power and thus you have to start it more often. This implies that by design I cannot park my Mustang at the airport when I go on a trip.

I am going to try checking the current draw and I will try turning the radio off now. But it sure is a pain in the **** to know that if you want to drive the mustang once a week in the winter you have to jump start it (in 7 degree weather that sucks).

How does your Mustang sound when it is having trouble starting? Mine makes a click every second and all power to the car is repeatedly turned off and on. It sounds like a master relay is killing power to everything (even the starter) when the battery is just starting to get weak. I know what the sound of clicking starter selonoid sounds like, but this is different. If you were to hold the key in START and repeatedly put your foot on and off the clitch (to release the starter safety switch) you could simulate the sound of this behaviuor. It almost seems that there is juice left in the battery and the ECU is making a decision to shut the car's electronics down every time the starter draws a current spike.

So what was the reason for your battery trouble? If you please.
