Went through puddle of slush everything started goin dim. died out when i got home. tightened the alternator belts and it still wont stay runnin. (will take a jumpand run for a minute or two. but then dies out) Any suggestions? (2002 kia spectra)

Bad alternator. happened to me in a big puddle. go to the parts store and they'll test it for free. you're running the car off of the battery. you will kill the battery if you keep going. the alternator is a pain to get out/in because there are several things in the way that must be moved. $100-$150 for the part, 1-3 hours to do it. have the battery tested after you're done. good luck!
