Just a friendly reminder that we aren't supposed to sell stuff in the general forums. That is reserved for the classified area.

1 second pulse. edit - with a DPDT relay in parallel with the switch contacts. Use the second set of relay contacts to prevent open and close signals from being sent at the same time due to a control error.

That is correct for the 802/803 machines. The 831 is different. He is working on the 831 first.

The frequency output of the PMA is the speed signal that is used by the governor module. Using a MPU on that one would be redundant.

Don't ignore the possibility of putting your own targets on the flywheel. With that method you control the number of pulses per rev. You need to use at least two in opposing positions to keep the flywheel balanced.

I'm having to do the same thing for my home brew governor.

You are choosing the more challenging machine to start with. These are a little different than your typical generator.

That I don't recommend because if anything causes the inverter to fault you get zero output even with the engine running.

The freq of the PMA would be the best thing to use assuming the controller can read frequency above say 100hz and 200v. Once it gets that high you are for certain not on the starter.

I would set it to kick out on oil pressure.

The alternator is an AC output. Its a 3-phase high frequency PMA (permanent magnet alternator). No excitation circuit needed. The schematic in the manual should be a big help to keep you going. Have fun.

Few quick things: The generator head isn't 60hz. Don't know if that is going to matter to you. Just don't expect 60hz from it. The actual frequency is much higher (300hz range). Engine speed is variable. It is load based from the governor module. There is no external input for speed control...

I don't think anyone here has gone down that road. There are a couple other auto starts that have popped up in posts but you will be doing some trail blazing. Have you you sat down with the wiring diagram and identified how it needs to be connected? The connection table for S1 will give you a...
