Message	Is there a test better than simply measuring voltage output, or total system voltage in general in order to determine the "health" of the alternator? Its been kicking out between 14.1-14.3 or so....... even with all the accessories on while cruising at 65mph so I really didnt think it was the issue......... I can always throw a spare one in to check it out to see if it solves the problem........... or possibly throw a charger on while the car is running to see if the idiot lights go out........... that MIGHT be do-able test..... any thoughts?
