I need some help I have no power when I turn the key or turn on the headlights if I cross the solenoid it will turn over but not start so I know the batteries have a charge I'm thinking a ground wire but not sure any help will appreciated

 

Update I tried a new ignition switch but didn't do any good. There is no power going to the starter terminal when I turn the key either. If I jump a wire to the s terminal it will start for a moment then die out

 

No idea what you are working on, but most Fords get their main power from a smaller wire at the solenoid. Usually someone was doing some work over there and have put this wire in the wrong place(it needs to be on the battery side) or they have been doing some wrenching with the battery still connected and accidentally shorted a wire and burnt the fusible link in this wire. The fusible link is a rubber looking thing in the wire.

 

Thanks for all the help I almost don't want to say what it was. I had some of the wires on the wrong terminal stupid mistake trying to hurry and it cost way more time.

 

Happens all the time, no big deal. Learning curve you know.
