The voltage is surging very badly when the car is first started and for the first few minutes you drive it. Does not affect engine, except you hear the cooling fan and AC fans surging up and down---but engine RPM is not affected noticeably. After a few minutes of driving, the problem goes away. I guess this would have to be a bad voltage regulator? I don't know whether the regulator in this car is internal to the alternator or external. If it is internal, do I need to get a rebuilt alternator, or is it something that a weekend mechanic can replace himself?
