I got my alternator a few years ago from the good people at NU AVIATION =
(Brian and his Mom). It came with a relay and an overvoltage sensor. It =
also came with instructions. The green wire is the alternator field and =
the yellow wire is for an idiot light on the panel. The overvoltage =
sensor and the relay go in the field circuit. Apparently the overvoltage =
sensor is a backup for the voltage regulator. When overvoltage sensor =
senses an overvoltage, it opens the relay.

Subject: REFLECTOR:Alternator wiring
Here I am, still doing wiring.
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.
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?
Has anyone got this figured out?
Hiroo
