2005 roketa 250cc quad

[firefighter66255]

I am having an electric problem with my 250 quad. I push the starter button and nothing happens. I did find wires coming from coil under fuel tank burnt. I replaced those wires with new. I replaced the left switch block a couple of weeks ago. how can I check the coil, and other items to see if they are working properly. I also need a wire diagram for the roketa RTS250 yr 2005. someone please help
