So I was out driving my car around yesterday and it got dark, began driving with the park lights on no problem, got darker so I switched the headlights on, as it got darker outside I could notice the lights shining on the pavement were flickering and the alternator gauge jumping around as they would flicker. Also the dash lights would flicker at the same time. What could be going on, is this a bad ground somewhere or a circuit breaker going out ? Maybe not enough power to the lights for some reason ? Where do I start with this.
