Hi Ed,
Is the belt showing any signs of slippage? Is the inside of the belt
shiny? It might be that one of your alternator diodes are gone reducing
the output. You can take the alternator to an automotive alternator shop
and he can test the diodes or if you have a VOM with a diode test function
you can test the diodes yourself. It could also be your regulator, but if
you are still charging, that would seem less likely.
