i was at the pollo loco drive thru with my bro when suddenly my lights start to flicker. next my battery light came on, then the my headlights shut off and then the gauges start reading 0. so i drove home with no lights hopping no cop would see me, glad to say no cop in sight. but i have never seen the needles just drop like that, i thought the car had shut off.

 

You might want to give the negative(black cable) a twist, mine does that from time time.
