Hi Norm,
Sorry for the additional message, but do you have the Engine information to confirm the Alternator installed? Using the Illustrated Parts List should help identify the alternator for your specific engine, then you can check the above Manuals for details on the Alternator you have.

As an additional resource, here's a link to the B&S FAQ on their Charging System Test to go with the .pdf files above:-
