2021 Kioti CX2510 HST - Not turning over - Safety system - Safety Control Unit Failure

This is a real DIY diagnostic on a 2021 CX2510 that won't crank, walking through pulling the seat, accessing the safety control module, and probing individual pins (PTO, seat, brake, start signal) with a voltmeter to isolate a bad module versus a blown fuse or faulty switch. It ends with the actual replacement part numbers and a temporary jumper-wire workaround. Best for owners troubleshooting a no-start condition themselves.
