Parasitic Draw

[speede]

I have an '04 Expedition that has a parasitic battery drain. The electronics system goes to sleep after 45 minutes and the draw drops to less than 10 milliamps and everything seems to be ideal. However, after about 3 hours, something wakes up that draws close to 810 milliamps. Any ideas?

I've checked the rear wiper motor park issue, but that doesn't seem to be the cause.

Use the test procedure vw uses, linked to the pdf in reply #4.

You will have to trip the door switch so that the modules go into sleep mode. Then it is a matter of finding the circuits or circuit with the draw.

Any aftermarket items? In the past forum members usually find their problem lies with some electrical item they, or the prior owner installed.

I found the problem! It seems that the DVD player wakes up all by itself!

Well their you go, now you have to figure out whether to repair or replace. Does the DVD have another item that powers it up? You may have to pull the unit completely till you find out why it's powering up. One of the other guys might have an answer for you. I don't have the wiring experience or schematics they do.

I'm thinking I'd love to just remove it...I started another thread looking for a block off plate or something. Even with 5 kids the thing was maybe used a handful of times, and gets in the way when you load the truck up. I'm thinking that I'll just pull the fuse. It looks like the only other thing that is on that fuse are the backseat controls for the radio.

If you can't find a block off plate, I'd give Crutchfield a call, they seem to have everything. We have a place called Tap plastics here in San Francisco that sell plastic. You can make your own, or pay them to make one.

OP - Is there a disk in the unit when it wakes up? Display closed?

 

[speede]

No disc in the player and the display is closed.

I'm wondering if the door switch circuit and timer have anything to do with this issue....
