radio killing battery
2008 xls, battery dieing withing 24 hours, did the resistor test to find the parasitic drain and found out the stock 2008 rockford radio is drawing 3 volts with key off. the radio itself is also off (well the display and sound anyway) but if I pull the 15amp radio fuse under dash the drain stops. sorry I do not know how many amps its drawing as i only have a volt meter and did the resistor test. any ideas?

I wouldn't expect to see 3 volts at the radio when it's off.. And if it's killing your battery in a day there's a problem...
Does the battery stay good if you leave the radio fuse out? Are any other systems affected?
Did you disconnect the battery and let everything reset?
I would probably pull the head unit out and see if the drain is gone... If that's the case a new HU is pretty cheap online or at a junk yard.

3 volts go away after radio fuse is pulled, i dont know exactly how the resistance test works I just know the battery draw stopped after pulling that fuse.
battery is fine and lasts for... ~ as long as that fuse remains out.
This did start happening after I disconnected the battery to remove the drivers airbag.

Yes, the battery has been connected and disconnected 3 times in total. I'm going to try and get ahold of a DC amp meter to get a better reading.

** so according to a Mitsubishi dealer that fuse also powers bluetooth and navigation, and I have neither of them... again with radio out there is still a draw on that fuse.

Okay so its fixed now.. it was the bluetooth module I didnt think I had, the buttons on the steering wheel hasnt worked since I got the car so I thought I didnt have the module, looking down in behind the radio I saw it mounted and disconnected it and the drain is gone. thanks for taking the time to read my posts.
second note, behind the radio is a harness that is taped up and out of the way, any idea what that goes to?
