my battery light keeps coming on. sometimes it stays on and sometimes it dont. I replaced the battery and alternator. today while going down the road, all my gauges pegged out to the right, when i let off the gas, they all peg out to the left, it did this for a few minutes and then just died. i took the battery out and charged it and it started right up. what else could it be??
