My BX1850 won't start and needed help on what to check next. Checked the battery and it reads 12.3v and the battery cable touching the battery is 12.3v. I checked all the fuses and they are good. When I turn the key I can hear the fuel shutoff click like normal and the dash lights up the indicators like normal. Headlights and turn signals work just fine. The tractor is not cranking when turning the key. Not doing anything when I turn it.
