What I'm saying is you have loads on the load side, so if you put a voltmeter in place of the fuse it will read 12 volts.

When I got it home I can check 12v with a voltmeter across both sides of the fuse. one side is 12v ground, the other side is 12v + so obviously something is shorted from the left side. This is the main fuse panel under the drivers left knee. I checked the white/red at the ignition/key block against the known positive side of the fuse panel and it shows 12v connectivity.
