Hey everyone.
Hoping someone out there can point me in the right direction. The fuel shutoff solenoid on my mower doesn’t function when I have normal power from the key switch. I have to put 12v to the shutoff via a bypass wire to shut the engine off. However if I remove the 15 amp fuse for main system the solenoid works as expected. On this model the solenoid is activated for 10 seconds ( powered) when the key is switched off .

this has me stumped - any ideas?

1st ..download the WSM (zd21-28..pdf) from kubotabooks.com

looks like the stop solenoid is controlled by the 'combination box. I'd carefully unplug all the connectors one at a time,clean, reinstall, say 2-3 times , to be sure they're mated,see what happens.
