I’ve read through the threads about whining alternators here and had no luck so I figured I would post my own. When I got my 94 the alternator was whining(it stops when you unplug the connector with the brown wire).
Instead of replacing it right away, I bought a new set of diodes and replaced those but nothing changed so I bought a brand new AC Delco 105 amp unit.
It still whines. Up and down with the RPM. I even checked all the grounds and cleaned them up. I’ve seen some people on here say that they’re alternator whine went away after 1000 miles or so but mine’s still going at around 4000+.
Has anyone been able to find a solution to this other than buying another alternator and hoping it doesn’t do the same thing? I feel like there could be a solution having to do with the brown-wired connector or maybe a heavy duty ground directly to the alternator case but I’m not sure.
Any help would be appreciated.
