White/Black Wire at ignition: 12.8v

Now while I was measuring those wires I tested them all and all of them but the grey wire read 12.8, the grey wire read 10v. Not sure if thats supposed to be that or not.

Fuse 1 inlet: 0.01v/0.00
Fuse 1 Outlet: 0.01v/0.00
Turn-relay in: 0.02v/0.00v
Turn-relay out: 0.02v/0.00v
Turn-switch in: 0.00v/0.00v
ON/OFF
You found the problem!! The white/green wire going out of ignition-switch powers fuse-1 and flasher-relay. Since you measured it with battery power leaving ignition-switch, but zero power at fuse-1 input, problem is with white/green wire in between. Fuse box is fine since power disappears before reaching fusebox.

Trace every millimeter of white/green wire from ignition-switch to fusebox. Use hook-probe or sewing needle to poke through insulation of wire every 3cm or so and measure voltage. At some point, you will find power at one spot, and no power 3cm downstream. Inspect wire segment in between; could be break in wire internally, or insulation may be exposed and inner wire shorted.
