Wtf white and black wires melted??

Prior to the melting I was blowing a fuse under the seat in order to make the headlight go on

However, this time, a different fuse got so hot it cracked the glass and further up on the ignition, the brown wire going to a black and white totally melted

And further all along at different points, white with black stripe wire was melting the wire.

Please look at pics

Does anyone have a 1988 kz1000p police bike wiring diagram?

Maybe I should rewire it back to the police version
But with different colored lights or something

Anyway I also noticed a ground coming out of the harness by the headlight --- not connected before when I first got the bike. Wtf

Look at the pics

This one is slightly different than the one in the Clymer manual, but I find this one to be clearer and easier to read.
