Thanks for the info. In answering the question, you introduced yet
another concept that is foreign to me<g>.
=20
It seems like I will need this "Alternator Solenoid". Currently, I have
two solenoids installed in my plane. One is tied to the master switch
and controls the current between the battery and the airframe bus. The
other controls the engine starter. =20
=20
I also have a wire extending from the panel mounted alternator switch
that is supposed to go to "Alternator Field", which, in my mind,
supplies the voltage necessary for the alternator to generate
electricity. Cut off field, and the alternator produces no power...
=20
Now, it seems to imply from the below statement that the type of
alternator I have requires another solenoid. From the sound of it, this
particular wire corresponds to the conventional "field" connection. So,
do I need another solenoid? Or could I simply connect the wire to the
rocker switch?

Had the same question and good folks in Co would not answer their phone
or return my calls??
=20
Local alternator shop said the green or S wire goes back to the B
terminal (senses battery condition and sets charging rate). The yellow
or L wire goes to the alternator solenoid to turn it on and off.=20
=20
=20
My alternator I got from Franklin guys in CO got me scratching my head.
Many of the airplane wiring references refer to three major connections
to the alternator. Airframe GND, Alternator Field, and Alternator Out.
=20
Now, as I look at my alternator, there appears to be four connections.
One is the GND which essentially is the casing bolted down to the
engine. Then there is a terminal that is marked with '+' symbol that I
figured is the OUT judging from the size of the bolt and nut on the
terminal. Now, on the side, there is a plastic connector that has two,
yes two, wires coming out. One is yellow and the other is green. They
are marked 'S' and 'L'. I am guessing one of them is the 'Field' but
which one?
=20
Has anyone got this figured out?
