Walt,
The voltage of a given lead-acid cell is 2.2 volts(ahhh rememberances of
in-organic chemistry). 6 cells is 13.2 at "full charge". The quotes are
there because the "full" changes with temprature. I'll have to look for
the numbers but most often it's quoted as a "xx.xxx specific gravity at 70
deg F. If you see 14 volts or higher you've got a problem.

Your number's sound ok to me Walt. Sears once told me a fully charged
battery off the shelf should be charged to around 12.75 volts.
Here's a couple of good links for alternator t-shooting.

Good luck,
