Hi Pat. No it is not normal. I have had the same on Ocean pearl and through my rather practical life on other motors in vehicles of diverse types. The excitation circuit is faulty. This circuit feeds voltage to the alternator from the battery. When it is not functioning, as you have found, the alternator self excites if you rev it. On my tmd22 the excitation was activated by tuning the key on and was routed through a voltmeter. (The voltmeter was incedental, it just happend to be in that ciruit and was a handy way to see it was functional) You may have a different circuit but it will be activated by turning the key on. My 24 volt alternator is excited by a feed from the house batteries activated by a solenoid activated by a feed through the start key from the 12 volt starting battery.
Search from your key looking for a separated wire or a poor connection.
