MECHMAN Posted May 19, 2010 Report Share Posted May 19, 2010 alternator out, with the a/c running lights on, highbeams on stereo up a lil sitting parked in the drive @ ~ 1000 rpm volatge in car reads 14.5v at front bat under the hood it reads 14.6v looking good i guess but it only took me like 20 min to take it out, this time i immediatley removed the grounding bar to prevent another mis hap im taking it up to autozone right now. they might not be ok at for testing h/o alts, but normal one right? Your alternator is fine. The voltage fluctuation you are describing is totally normal, a function of load and temperature.
