I am having some problems diagnosing an unusual problem where my instument panel dials (fuel gauge, oil pressure etc.) will flicker like its not getting power; i experienced tghis problem before where the dials would flicker wildly plus the 'srs' light would come on, but i had the alternator rebuilt and this problem disappeared.
this problems seems to occur whjere i have the headlights and ac on at full power, but i tried parking the car and turned on the defrost, the ac, the lights, the wiper while at low idle and no flickering occured...is this a fluke or is it some kind of bad wire shorting out etc.?
