low battery voltage.
i have a 86 n/a and i recently put in a optima red top in it. over the last weekend my car died and i tested the battery and it had a bad cell so i replaced it. then found out my alternator went bad too so i replaced it also. now my car runs but my battery registers 11.5 volts when the car is of and about 12 when it is on. when i rev the engine there is no change in volts or amps that are coming out of the alternator. anyone have any idea's or had a simalar problem?

Are you reading that off the stock dash gauge or are you using a DMM on the battery. If you're doing the former, do the latter instead.
If your readings are right, your alternator is most likely dead.

put this to a volt meter and make sure the alternator they gave you isn't defective... it happens. that or make sure you put back everything, i know that sounds stupid but it happens. check all connections
