Dino Alternator connections

Just bought a new Alternator from Superformance (pity the key is a different size to the original) ...now I forgot how I took the old one off and note there are three connections :

I assume the big nut is the Battery....but then there are two push connectors ...

Which one is the field ??

What is the other one for .....should it be earthed. ?

Finally...are these self exciting ??


Thanks

 

I think I have worked it out but confirmation would be nice

Out of the two push on connectors one goes to the slip ring brushes .... So I assume that's the field connection ???

Not sure where the other one goes

Thanks

No markings by the way

 

Thanks. That's clear now. The hidden one goes to the brushes so that's the field.

There was no third wire so I assume the light is not connected on mine.

Anyway thanks for input
