Carl - Low generatory output can be caused by several things:

1 - Slipping drive belt(s)

2 - A tired generator (worn brushes and/or commutator, failing internal connections, etc)

3 - Excessive resistance in the wiring harness between the generator A terminal and it's connection to the ungrounded battery post.

If you have a decent DC voltmeter place one lead on the generator A terminal and the other on the ungrounded battery post. With the generator running at full output the meter should indicate no more than a few tenths of a volt. Anything higher says there's high resistance somewhere in the harness - most often at or near a terminal.
