1993 Buick Skylark changed battery and aternator, but car r

You mean when key is off as in overnight? ,If yes have a battery drain test done some circuit is stayinf powered up.

i changed the alternator and battery in this car, but the alternator is still not putting out. i found out that the car is just running on the battery. i got the car started again and disconnected the batery and it stalled. so i am assuming that the alternator is faulty or someone said that this year of car still has a voltage regultor. i dont think they should be in the alternator. do you know i look and didnt see one. also to change the belt do you have to release the ider pully because there is no tensioner on this make.

Regulator built in alt. Check ERLS fuse and Gague fuse. Also chek to see if power is going to Red B + wire and smaller red wire on plug. You have a tensioner on this site go to Popular Site Links click on Drive belt routing diagrams and fine the location.

thank you docfixit, i chexcked fuses they are good . one more question, for now, with a volt meter do i use ac or dc volt to check red wires leading to alternator.

Use DC also check ground from battery to fender
