Default Alternator or battery?

Hello, my wife's car (2014 avenger, 2.4) recently had all the dash lights blink on and then off and the traction control light stays on. Also the radio lights turn off and back on. She went to advance to get the battery test and they told her that the battery reads too low for an answer. I was told it could be the alternator from an avenger group on facebook but i was hoping for a second opinion before I replace the alternator this weekend. (I heard a surging alternator can harm the ecu.)
Thanks

Stick a voltmeter on the battery with the engine running. Should be @14.5 VDC. If so, the alternator is good.

Directly to the battery? Because its in the fender. Would i get a good reading from the positive post that leads to the battery and a good ground?

Our 2013 has the same symptoms as yours. Did you ever figure it out?
