    2008 Expedition we have total electric failure. Nothing is working. No lights, alarm , radio , nothing. I suspect it may be a fuse or relay but which one? is it in the kickpanel or under hood? What number might it be? Help!

    Welcome to the site.

    Anytime you have electrical issues you always check the source voltage first. Your battery should read 12.6 volts fully charged.

    Battery is good. Is there a Master Fuse and what is it called?

    I'll look when I get home and see if it has one, but they are usually called a mega fuse. Ford also uses fuseable links on a few circuits.

    What is your battery voltage?

    I only have diagrams for the F series trucks for 2008. The 2007 only used fueable links to the alternator and one to the sjb. See if the fuses in the sjb have power as it is hot at all times.
