There is a relay that you probably need to check. It maybe like mine and it would be located in the fuse panel on the passenger side floor board (not quite sure where your panel is) but here try this link it will help https://www.startmycar.com/us/ford/exp…

If the alternator is not charging the battery, the battery will eventually drain and the vehicle may not start. Here are some things you can check:
Check the alternator belt: Make sure the alternator belt is tight and not slipping. If the belt is loose, it can cause the alternator to spin too slowly to effectively charge the battery.
Check the alternator connections: Make sure the connections between the alternator and battery are clean and tight. If the connections are loose or corroded, the alternator may not be able to effectively charge the battery.
Check the alternator itself: If the alternator belt is tight and the connections are good, you may have a problem with the alternator itself. You can have the alternator tested at a local auto parts store or mechanic to determine if it needs to be replaced.
Check the voltage regulator: The voltage regulator is responsible for controlling the voltage output of the alternator. If the voltage regulator is faulty, it may cause the alternator to not charge the battery.

If everything worked be for you took fuse panel out I would start there. I had to replace fuel relay but I cut connection wire from plug and put relay that was easier to get to and there’s a wire that shuts pump off so it wouldn’t flood the motor fine it and hook to relay but it will still run even though you just wire in new relay - the problem with taking fuse panel and replace relay is it could go out again it gets hot behind the panel and that’s the problem usually

It has a brand new battery. I checked the fuses, battery terminals, +/- cable; all connections are good. It starts when it wants to and randomly won't start. On the occasion when it doesn't start, I hear short squelch behind the AC control panel, when the key is in the on position.

My car went into the dealership for a recall repair. They called and said my battery died, but they called Autozone and I should have a warranty because it is only a year old. So they returned my 2016 expedition back to me with a dead battery. I put in the recharged battery and have had numerous electrical issues. Unlocking the door with the remote makes the alarm go off until i unlock the doors. The check engine light and wrench light go on and off. The need gas light comes repeatedly on, even when it is full. Starting the engine is scary. It either starts after it cranks a few times then tur… Read complete

This truck has been sitting for about 7 years, and well mice have been in there. There was a lot of mice droppings, sometimes I can hear mice in there running around, and I assume they have bitten some wires because the battery dies within a day if I leave it hooked up and if I take off a terminal the battery stays charged. There's 20 fuses that have power and I need to know which ones shouldn't have power so I know what wires to chase down. The fuses are 1, 2, 3, 4, 13, 14, and 31 for the cabin fuse panel. And the ones under the hood are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. All of this… Read complete
