Question about 1994 Oldsmobile Cutlass Supreme
I jsut replaced my alternator and battery and my car still shows low./varying voltage on my gage in the dash. when i put up the windows my volts drop by 2 and when i get on the gas the voltage goes down as the rpm goes up. sometimes the car works almost perfect but most of the time i have this issue sometimes it gets so bad that i can not drive the car because it gets down around 8 volts and almost dies. im almost about to give up any ideas would be great
Check all of your grounds from the battery, the one to the starter or the one to the frame may be corroded or bad

It soundls like you have a high powered sound system and you might have to step up to a higher amp alternator, that will give you enough power. Your battery should be fine too. Try to find out if the voltage regulator is built into the alternator and if not ask to find out where it is on the car and replace that to.

Check the battery ground cable and make sure that you have a good engine ground.to do this you need to use a voltmeter and check for voltage drop between the battery terminal and engine it should not be more 0.4 volts .if that is o.k. the alternator internal voltage regulator is not good and replce the alternator again.also make sure the drive belt is tight.
