Default RE: 2005 Mustang GT Dead Battery

I've had dead battery problems as well with my 05 GT standing for just 2 days - after 1 day its a little hesitant when starting.

having trawed several forums It is clear this is a common issue !

This is where I am up to: a quote from my post on another forum :- dead battery

Ok, I just got in from testing my cars current drain in the cold -2.0c which for us brits is chilly!

the car has been stood for a 24 hours & before I started, I checked the battery voltage and it was down from 12.4 yesterday to 11.8v !

I unclamped the negative cable from the battery and used an amp meter in line between the negative post on the battery & the cable .

for the first 30 secs or so the amps fluctuated around 2 to 2.5 amps then settled at a steady 1.1amps during this time the interior light stayed on . I couldnt see from the manual which fuse to pull to turn it off so I just opened & closed the drivers door to force it to switch itself off. that done the amps reading dropped to a steady 0.39amps

then I pulled the shaker 1000 amp fuses - fuse 6 & fuse 9 . Fuse 6 caused a drop to 0.12 amps . Fuse 9 made no difference, I then prceeded to pull in turn every other fuse and relay in the power box under the hood but no change from 0.12 amps. I tried the fuses inside the car but could easily get to them all so only pulled about half. no change to the amperage though.

so in the end I pulled both shaker 1000 fuses ie 6& 9. and the amperage remained at 0.12amps.


there is clearly something wrong with the fuse 6 circuit but I dont know how to proceed from here.

The car just about fired up & after running it for 10 mins or so the battery voltage was 12.80 . I guess I need to check it again tomorrow to see if the voltage loss is reduced."
does anyone here know if 0.12 amps is a reasonable current draw when everything is "off"`including the alarm ??

I am in the Uk so cant get any warranty help from Ford.
