Gary :
My suggestion would be to buy a (cheap) multimeter and do some tests
before blindly replacing the alternator. Harbor Freight frequently has
a digital one on sale for $10 that is adequate. It is rugged (and
cheap) enough that I carry one in the trunk.
There are many different bad connection problems that can masquerade as
a bad alternator.
As Dave noted, the stock Lucas alternator has an internal regulator, but
it's possible someone has installed a different alternator with an
external regulator.
