Cannot start my Hayter 13/30 ride on mower?

Cannot start my Hayter 13/30 ride on mower. All of a sudden it won't start. I replaced the plugs and ignition switch , but it still wont turn. It's like there is no power.

I have replaced the solenoid, I can hear the solenoid click when I turn the Key, but still on start.
