Alternator and Battery replaced, won't hold a charge

Alternator fuse. Look in owners manual for location of fuse. If no manual Google year,make and model of vehicle.

Check the fuse as stated above or you could have a bad connection from the wires to the battery. A loose connection will cause the battery to die.

Had the same problem, Turned out it was my back wiper trying to run as if it was left turned on. Because the wiper was constantly trying to run, it drained the battery.

A few weeks ago my battery light came on on my way home then eventually after a hour if that it nust cut off when i stopped at a stop sign....got a jump start and it made it two blocks....then it cut off again....then it made it maybe a half a block before cutting off again....got another jump start and it didnt even make a half a block....try to jump it again....it crunk made it a few inches before cutting off again end up having to get it pushed home. So once making it home the guy that pushed it home said it prolly was the alternater since the battery light stayed on....so bout a week later someone i knew took out the alternater took it to the part store they ran all test and said nothing was wrong with it and to check the battery cables changed them got the battery charged wouldnt takea charge got a new battery and the cranked but only stayed on a few seconds put gas in it and the samethomg happend wouldnt stay crunk and the battery light still on,what else could it be?
