Welcome to the site !!
I am guessing you got something to do with the kill switch wet .... it is possible that it is grounded internally from water , that will prevent it from starting so it might need to be taken apart and blown out with air , or just blown out with air ..... water will prevent the bike from starting if it is in the kill switch , otherwise , you will need to pull apart any electrical plugs that you can physically see that are not under a panel or the tank (wires behind the headlight I would check) , again , checking for water ....
Basically , you need to blow out every connection , and if that is the issue , then I would get some Dielectric Grease , and coat each connection with it , then put them back together , that will prevent water from getting in again .... and DO NOT use a Pressure Washer on any electrical connections or the kill switch when washing the bike ............
