Tachometer input signal.

Is the input signal for the tachometer on the M series tractors AC or DC voltage?

And the tachometer gets the input from the alternator?

Signal is a pulsating DC signal ( probably 0 to +12v ) from alternator going to the 'meter panel' through a wht/grn wire that's joined to a wht/yel wire.
