A loose or worn serpentine belt can cause low voltage. I just had to trace out an electrical issue in my bkazer. Turns out tge worn serpentine belt slipped quietly at low rpms and couldbt turn tge alternator fast enough to produce enough voltage to power the vehicle. So my battery was taking on most of the electrical acessories and not charging so after a while.....no juice

Can a bad serpentine belt cause alternator problems?
a serpentine belt runs the alternator and the more stuff you have running (heat, lights, radio) it causes the alternator to have to have the belt run faster to supply power to the things that are running. if your belt is loose or worn, it will slip and cannot provide the amount circulation needed for the alternator to produce enough sustainable power to run everything at once. the belt itself runs several components, and if the power steering goes out as well, then most likely that you have a bad belt. you can always try tightening it with the idler pulley. but if the belt is too worn or stretched, then i recommend just getting a new belt entirely. cheap fix really.
