It's a automotive type. While I havent' connected a meter to the field to see if it's off during cranking I assume it is. I'll check however.

During the last survey the starting battery was not connected, even though the battery cables were near it. It was also wired to use the house batteries through a switch. I've since removed the house battery connection. I do have a method of connecting the two banks together but have not had to do so. > > > From my distant and hazy past I know that there is a special wire > going > to the sense side of the alternator.

It's too long (3' or so) to be a fusible link. I suspect that it may be for current limiting purposes perhaps? Or as you said a way to boost the output voltage slightly. I'll measure the voltage drop and see how much it is.
