alternator test - diesel engine

How do I test my alternator to test whether or not it''s charging my battery?

I have a diesel engine (Westerbeke 27).

Someone suggested that I disconnect the positive terminals of my batteries. If the engine keeps running, that means it''s not working off the batteries. Problem with that, in my mind, is that a diesel engine doesn''t depend upon sparkplugs as a gas engine does. So what would disconnecting the terminals tell you?

So any suggestions?
