yea! so everything was fine yesterday until I went to start the jeep. Cranked right up, my battery light came on, and I noticed a very loud whine.
The whine noise varies based upon rpm.
I used my superchips to pull a "charging system output high" code.
After some google research, I checked my battery cable and tightened the accesory wing nut. Battery light went away and after clearing the code, it no longer appears.
PROBLEM. I still have a terrible whining noise.
Had advance auto parts check the batter and alt... they say both are GOOD
Had autozone check the same and they say my Alternator is BAD
Does anyone have any experience with this? Does this sound like an alternator issue?
So long as the jeep cranks and runs, could there be any problems if I do not replace the alternator right away? ie electrical issues?
