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.
