Thanks in advance for any and all help....

My wife drives a 2006 Mustang v6. It is equiped with the factory shaker 500 stereo system. Recently we have been having problems with the battery going dead. I put an amp meter in line with the negative terminal and battery cable and started pulling fuses. I have a 1.5 - 1.8 amp draw with everything turned off and all doors closed. When I pull the stereo fuse in the engine compartment the draw goes away. I know the stereo draws a small amount of power to hold presets and such, but 1.5 amps seem way too high. Any sugestions????

yes 1.5 amp draw will kill a battery over night! It should be around a 100milli amps.there maybe a problem with the deck not turning off,i remember reading something about this.Have you tried turning the radio off,before turning the car off?

 

Joe, very common with 05-07 mustangs. I still have my original battery, but i place it on a tender overnight.

 

I have a 07 that just started to act up. A little history. I had a coolant leak and it was blowing in to the engine compartment. I replaced the degas bottle. Shaker 500 died. Battery started to die. ( 2 days in garage it was dead) After jump and full charge the battery was at 750 CCA. I have read many threads on this issue. My problem may be that coolant got inside the alternater and screwed this up. I am going to do a test to it and see. I like you are not a very happy pony owner. Let me know if you have any other issues.

 

Actually it should be half that(page 15 of that link, <=50milliamps) or below.

You'll have to replace the head-unit. Since it's out of warranty I'd just go with a cheaper pioneer double-din dvd unit myself. Get more from it, sound better, and won't kill your battery.

 

DO YOU THINK THE SHAKER 5OO KILLED THE BATTERY. I PULLED THE FUSE TODAY AND JUPMED IT, DROVE APPROX. 1 HOUR. WE WILL SEE IF THIS DID THE TRICK

 

I can't say for certain. You'd have to use the diagnostic/testing procedure in that service link I posted previously to know for sure.
