Was driving down a dark stretch or road, wen to switch my brights on and the second I pulled the lever back, the car died. No lights, hazards, interior lights, nothing. Pushed it off the road and got it towed home. opened the door and the interior light went on. I then went to test the headlights and light went off, nothing again. Tested the battery and it is fine, what could be going on here? Really dont know where to check. If the car sists long enough, I get a little bit of life but thats it. And the battery is fine. Tow truck driver said it was the alternator, but that doesnt make much sense. If anyone has any clue about this, I would really appreciate the help. TIA
