My 1994 F250 has no power! Battery has been checked, the grounds look good, negative and positive cables are tight. Fuses are all good and have been swapped around as well as the relays. Battery has been charged, even tried to jump it off at first. No headlights no start nothing at all. And of course my windows are stuck down to add insult to injury! A local auto parts guys told me to try here. So does anyone have any ideas??????
