> Specifically, what are terminal "D+" and "+"?

"D+" is generally the terminal that goes to the warning lamp on the dash.
The other side of the warning lamp should be wired to switched 12v.  Some,
although not all, alternators rely on the current through the warning lamp
to "get started" after you start the engine.

If it's a big terminal (or two) "+" would most likely be the output to the
battery, although my Bosch alternator has it marked "B+" instead of simply
"+".  Or if it is a smaller terminal, it's probably the "sense" input, which
should also be wired to the battery.
