It ends with the actual replacement part numbers and a temporary jumper-wire workaround. Best for owners troubleshooting a no-start condition themselves.
Posted by the Jon Heimer channel, an owner working through the repair on his own tractor rather than a dealer or technician.
A bad safety control module can block the start signal even when switches, fuses, and battery voltage check out fine, as found by probing the module pins.
Probe each numbered pin on the safety control module plug with the key on; a working switch shows about 12 volts and drops to zero when activated.
Yes, jumper pin 17 (start signal input) to pin 26 (start output) to bypass the module, but this disables all safety functions and is temporary only.
The old module was TB15-000022A; the replacement sent by the dealer ended in 0085B, suggesting an upgraded version.
