Hey all, new here trying to figure out an issue with my truck it's a 92 f250 7.3 idi the voltage gauge is bouncing around while driving it's at the L in the "normal" usually today is the second time it's done it to me it's got two new batteries and alternator. I'm wondering if the voltage regulator my be playing a part in this while the gauge is bouncing around I can hit the brakes and when the lights come on it stops or when my head lights come on it stops for a few moments then starts again then randomly it will stop bouncing around for a while then randomly start again if my head lights are on while it's doing it they will flicker till the gauge settles back down any help would be much appricated
