kubota b`750 dead, not instrument light, no start

[mtnsheep]

while painting my b1750, reattached rear hazard lights, then started tractor, couldnt use key to turn off, so pulled shutoff knob. Tried to restart and nothing, no instrument lights, no starter, no lights. Battery is good, all connections good. Could i have attached the wrong light wire and shorted something? 2 fuses 15a are good. Would this be the fuel off solenoid gone bad as coinencedence? Thanks for any help. Yep, checked only safety switch with the clutch pedal. Glad to be on this forum.
