Polaris 09 500 no power

Polaris 09 500 efi ,no power. I have voltage to the and from the 20 amp main fuse. The schematics show a yellow wire direct to the ignition key switch I have no power at the ignition switch. I don’t want to open up the wiring harness at this point until I know for sure there isn’t another connection along the yellow wire. Can anyone confirm the straight run of the yellow wire ?
