I have a 2000 Expedition EB 5.4L, I've checked my alternator and battery and both check good. Every morning when i go turn the truck it wont turn, unless I hook up the battery with jumper cables. I checked with a meter on the negative terminal being disconnected from negative post. The meter read .50 amps, but once I removed Fuse # 103 which is Junction Block Battery Feed, the meter reads zero. Has anyone had this similar problem and what was your solution? Thanks would really appreciate any help.

 

Maybe these videos will give you some help.

 

As posted 9 years before in the other thread by projectSHO89:

F103 supplies the under dash fuse box.

Go to it and continue your process of pulling one fuse at a time.

One caveat: You should bypass the driver's door latch so the GEM thinks the door is closed, then wait for the timeout - around 30-45 minutes - for the battery saver circuit to power down.
