There are 3 wires in a box in the back of my alyernator, where do they attach. electrical marine boat engine?

I have a picture of them on my phone. 2 wires are green. The last wire is orange. I couldn't post the pic but I have a pic of it on my cell phone. Thank You, Chris 1986 350 boat engine

There are to many alternators out there to say.Look to see who made it and contact them.Any number on it will be a help when you contact them.

I'll GUESS that they *may* be the two positive 12VAC outputs from alternator, and common negative (ground)which would be hooked up to a bridge rectifier, to give you 12VDC.
