So I just got my Evo 8 and I noticed sometimes when I have the headlights on and turn on my turn signals or something my interior lights will flash and my volts will go wayyy down. I went by Auto Zone and had them test the battery, alternator, and starter.. The test came back replace battery.. So I did that. Now the problem isnt AS bad but it is still there. If it is doing it, and I turn my high beams on my car will hesitate BAD. If I do it 2 or 3 times it will stop and act like it never happened!!! Do you think my alternator has gone bad even though the test read that it was fine? Thanks for any help!!
