2013 Sonata 2.0T new battery and alternator, why isn’t my alternator charging the battery?
What is your question?
I have a 2013 Hyundai Sonata 2.0 T. The battery warning light came on while I was driving the other day. I got home and figured it was most likely the alternator. So I went and bought a new battery and alternator and installed them. Alternator was still not working, so I exchanged it for another alternator and still nothing. I have checked all the fuses and relays, charged battery up on a battery charger. And even tried to have it tested although the parts house claims that this alternator has a clutch inside that has to have power running to it to be tested. The car runs if the battery is charged up but it will die as you drive if you aren’t careful. Please help.
What makes this problem better or worse?
Full Battery Charge or Replaced battery but it’s only temporary

Testing is needed. You can guess at components, but what if it's something else? I would first have a very close look at the wiring harness to the alternator to ensure all wires and terminals are intact and not damaged or burned. Circuit testing beyond this may be required. You may want to obtain a known good alternator from a dealership as well -- but that assumes several alternators are bad.
