I'm wiring my experimental per Z-11. I have installed a Continental IO-240-B which came (new) with their (TCM) 60A Alternator installed. This alternator has a threaded terminal identified as 'Stator', as well as the terminals marked Battery, Field, and Ground.

Can anyone tell me if this alternators 'stator' terminal needs a connection of some kind? Or leave it unconnected?

A search of the archives revealed nothing to me, nor did the Continental Engine Operator's & Maintenance Manuals.

Thanks in advance for any advice.

The "Stator" terminal is the center tap on a "Y" connected
stator winding. This terminal has been used in a variety
of ways to sense whether or not the engine was turning
the alternator, as a signal to drive various alternator
failure detectors, ect.

I've not seen a useful application of this signal in years.
It exists only on alternators with "Y" connected windings.

In any case, you can ignore this terminal.
