I'm fixing a damaged aircraft. I can't get the alternator to work and I have never seen it working, it may just be broken. To pull the engine I had to pull the leads and I don't know that I've rewired correctly. This is the model;

It has a plug with three leads
E _
F| | N
E is Negative
F is Field
N is Stator
There is a small metal box on the alternator. It's already has a hard wired ground, and one red line in that goes hot when the alt switch is on and one green and a yellow line going out that I know went to two of the pins above. Which is which?!
I've tried wiring this in several configurations, but none appear to make current.
Where do I start diagnosing this? What is the little metal box doing?
