#156 of 197 2005 Mustang GT Electrical Issues by jtmccall1

Aug 27, 2010 (9:23 am)

I have a 05' Mustang GT and have had an electrical issue for as long as I can remember. I should mention that I had satellite radio installed in it very early on at Circuit City, not sure if that is relevant.
My car battery goes dead in a matter of days since new. Ford told me to make sure my radio is turned off before I shut the car off each time. I do this. Still the car goes dead quickly. Then they had me replace the battery. I had my dealer put in a new battery. I still have the same problem.
I saw on another "Ford Forum" site that supposedly there is an issue where the radio system draws 1.64 amps instead of .11 as it should. It says Ford is aware of this problem. I called my dealer and neither the service manager or the electrical guru service tech ever heard of the issue. I know I'm not the only 05 owner with this problem. I keep the car on a trickle charger most of the time now but the other day (with a full charge) after sitting at my office for 8 hours, I went to leave work and it wouldn't start. I waited 2 minutes and it fired right up like there was no problem but as other people have mentioned, the radio came on to AM540 and the CD's cycled through and the guages did a complete reset. Can anybody help me with this?

My understanding from various forums (though I don't yet own a Mustang) is that there are several draws on the electrical system when the car is 'off' besides the radio. In addition, the alternators aren't the best, so the batteries aren't always charged to full. Have the alternator tested to see if it's fully functional.

Not really an electrical "problem", but a request for help. I've been looking for an Aux Audio Input Cable for a 2007 mustang gt. More specifically, I need a wire that will allow me to connect a thumb drive to my auxillary input in the center console. I have looked online for a few days without success. Anyone have a site for this wire? Thank you in advance.

Umm......what exactly do you think is going to read the thumb drive? You'd need a mp3 player to interface with an aux input or something to actually read the thumb drive like Sync. PIE makes the adapter but again you need a mp3 player.

Thank you. It's actually not for me, but for a neighbor. I use a thumb drive, but mine is in a new toyo that doesn't need anything additional. I didn't know how it worked with ford / 2007 technology.

I assume that when I took the car to the Ford Dealership that they looked at it and tested it. Prior to taking it to the dealership, I had a friend look at it and he informed me that the alternator was putting out enough volt's, if he was wrong then I firgued that the dealership would have caught it.

First, I can't speak for the older Mustangs, but the '10 and '11's with the electronic package will read music files off a thumb drive without benefit of an MP3 player. They have a 10Gb hard drive in their guts that stores music. They even replaced the 6 CD changer with a single CD drive because folks don't need all those CD's anymore.
 
Second, assumptions about what dealerships did or didn't do are dangerous. I think Autozone stores will check batteries and alternators - you might want to take the car there. My armchair diagnosis is that you've got something in the car drawing electricity even when the car is off and it's killing your battery.

Yes, they do have a 10gb hard drive but you can only load the hard drive from CDs one at a time. Even with Sync you can't load mp3s from the usb drive to the jukebox hard drive. Without sync there isn't even a usb port.

Without Sync (and the Electronics Package), there's no hard drive. Guess you'd need to insert CD's one at a time, like the old days.

No, the hard drive is part of the Navigation system. The Nav system has a 40 gb hard drive and they found they had 10 gb left over and made it available as a jukebox. Since there is no connection between the Nav system and Sync you can't use the Sync usb port to load mp3s from sync into the Nav jukebox.
 
That may all be different with the new MyTouch interface but mustang doesn't get that yet.
