From looking at your photos, it looks like the alternator is indeed under the bracket with the solenoid on it. From what little I can see of it, it is probably a 105 amp alternator. The amperage should be stamped on one of the mounting ears of the alternator. I would try to remove that bracket to get at the alternator--a silly question, does the alternator have a seperate belt, and is it there?
Also, a wire going from power to ground would not be conducive to proper electrical operation, try removing the "ground" wire, and see if you voltages improve, although I would think it would have fried off something somewhere if it was indeed a ground with all the hot wires with it.

Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.

It appears that your isolator has been replaced with a relay. I have the same situation on mine 1984 MH.

Here's the thread where all of this is discussed. You might also want to try a search as there are other threads which discuss replacing the isolator with a relay.
