Ignition fuse blowing

I have an issue I think may be starter relay related but not sure. 2005 450 with the 4 wire relay just like the picture in starter relay sticky. Has brand new main wiring harness and handlebar start switch harness. New cdi box. Got everything connected and it started. (Purchased non running). I connected everything up and put some plastic on it. Was going to drive it around the yard and as I started it it ran then acted like it wasn’t getting gas and quit. Everything was dead. Blew ignition fuse. Replaced and blew as soon as key turned on. Check fuse box and when ignition key is on it shows 12 volts from one side of ignition fuse to other side like it has a short. I unplugged every connection on the harness. I even disconnected the cdi box regulator and the wirrs that go into the stator. The key switch the run button and the starter relay are the only three plugs that changes it to no voltage. It acts as if it has a direct short. I can ground the volt meter or touch the other side of the fuse and both have 12 volts showing. When I saw the picture of the starter relay I checked my new one I got from yamaha today and the 2 spades closest to the battery and starter lugs are marked + and -. These 2 spades are direct short according to the multimeter. Are they supposed to be? Is what I am seeing so far the way it’s supposed to be acting? I planned on going to yamaha to test a new one to see if they had same results but wanted to ask fit’s just to get input. Thanks for any help.
