John Deere AMT 622 ,no power to ignition switch.

[Rexy boy]

I have a John Deere AMT 622 with brand new motor( 20 hours on motor) . The motor came complete ,new starter ,new regulator ,carb etc. A few days ago I lost all power at the ignition switch .No Lights ,No lift bed, no starter . Isnt there at least supposed to be power to the ignition switch? I have no power to the ignition switch . Any ideas ?
Thanks Larry
