Good advice.
Right....no gauges or warning lights. It no longer goes through the warning light start sequence, but it starts immediately when I engage the starter. Other things like the four-way flashers work. I am primarily running it to see if there was something I missed in the instructions or in machine settings.
Somewhere there is a magic electronic module that has failed. I haven't found it. One equally curious event in the pre-pre-pre-failure mode is that for a short while, the engine would cut-out if a raised myself out of the seat, even with the shift in neutral, and at idle, feet off everything, no other implement drives engaged, etc. It was then a subsequent surprise and change of failure mode that the engine would not stop regardless of shifter position and I was no longer seated.
