30 amps is awfully small.  I daresay you won't feel as good the first time
it's a bit hard to start (or you left the lights on), and the fuse blows
when the engine starts.  All it takes is for the battery to be down a bit
and the alternator will go to full rated output (or even a bit beyond) when
the engine starts.

That is actually as it should be.  The ammeter reads current into or out of
the battery, so it should be close to zero most of the time (meaning that
the alternator is supplying whatever power the car needs, and the battery is
fully charged).
