Start with brushes, they're the things that wear out (and symptoms of worn
brushes are was you describe). You might want to think about replacing
the bearings too, if possible.
Other things that go (with different systems) are the diodes, and the
regulator. This might be a regulator problem, but as the brushes are a
wear point, I'd start with them.
Are there brushes in an altenator? I'm not trying to be a smart a** here, I
really don't know, but thought since it's an AC generator they were brushless.
I've only worked on generators which DO for sure have brushes, but always just
exchange altenators. The symptoms described above make it sound like a bad
diode, causing just half-wave rectification, therefore less current available.
