Help with no power??

If there's no short with the key off, then if there is a short it would have to be in the wiring that is gets power when the key is in Run or Start, but not protected by fuses.
However if this occurs, the ammeter will clue you to this happening. With the engine off, battery connected, turn the key to run. If you see it show more than a 5 amps discharge, something is up. Same with key in Start.
