I own a 2014 Edge limited. I replaced the alternator and have had the battery and charging system checked. When slowing the door locks reset, the charging system alert comes on as well as the dash dims. It also occurs when I begin to move after the stop. At night the headlights dim and then come back to full power. Last night on the freeway all the lights came on suddenly then emitted a bright flash and back to normal. Any suggestions would be greatly appreciated.
