    5.4L 3V 2008 - "genmod_ls" = "fault low" - P0625

    Hello, I'm from Germany and I'm working together with an experienced Ford mechanic (specialized in 7.3 Powerstroke) on a Ford Expedition of an acquaintance. It is a Ford Expedition from 2008 with 5.4L V8 3V. It has a gas system installed and the previous owners have made a few messes...

    Alternator Wiring Diagram/Wire Colors?

    Hey everyone! My 2015 recently started kicking out a 'check charging system' warning. I checked the voltage while it was running and it showed ~14.5V, so I figured the alternator was good and the original battery just needed to be replaced (which obviously put in its time). A new battery didn't...

    Using Expedition as backup 1kW power

    Where I live we don't have power outages often. So, I don't have any power backups, generator, etc... But last week there was 3 hours long outage. And it was really inconvenient. Especially since I'm working from home. I have UPS, but it only lasts 7-10 mins. I can buy the generator, but then...

    Check Charging System (Zombie Battery)

    I know there are similar posts already, but I haven’t seen one with this exact recipe… I purchased a 2004 Lincoln Navigator with 239,000 miles on the odometer. Over the two-hour drive home the “Check charging system” flashed periodically and the battery light came on periodically (though not...

    Hello all, newbie here. Firstly I want to say sorry for the long and sorta convoluted post, I am not really sure what is happening and mechanics have been unable to help. I recently purchased a 2007 Expedition Eddie Bauer, it seems to have been a barn car (I actually found hay/straw tucked...

    Can someone please explain

    So, I am a new Ford owner of about 4 months and the other day my Expedition overheated. Ok, not a problem found the leak fixed that topped off fluids and now the dang thing won't start at all.

    The "Check Charging System" warning that won't go away...

    (2006 Expedition, 194K miles) A few months ago, I got my first "Check Charging System" error. It would come on intermittently, and go away when the engine revved up. I took the alternator to the shop, surprisingly, it tested "OK." The problem went away for a while. Recently it came back, only...
