Infinity 97 - battery is one yr old as is alternator. Drains completely overnight after being charged. Need ideas.
Sound as you have a short in the car that is draining the battery make such everything on the battery is tight. I would bring the car to Auto Zone and have them do a load test for free to see if the alternator is good, just because its new does not mean its good. Check to make sure all the switches are off in the car
You have a parasitic draw. You need to test each circuit in the car to see what is draining your battery. youtube has a few videos on how to perform the test using a multimeter. Good luck
