Actually just replacing the battery with a new Delco will do the same thing.
Since it was a "change parts until it works like you want it to" type of
diagnosis it's a crap shoot as to what fixed the real problem if it is fixed
at all. Get a manual and a volt meter and check it out in a systematic
manner, otherwise find a good repair shop and take it were it can be done
By the way, much "under" 12 volts and the computer will shut your Corvette
down. The slight dimming of the lights when another load is added is normal.
With the age and amount of miles on your car I would assume it sits and may
have had to have the battery recharged. If that is so change it and bump up
the CCAs a few hundred and drive it more often.
