The alternator on my 180hp Lycoming is putting out a whine in my
headset. My a/p recommends a replacement. It's 7 yrs (about 600 hrs)
old. Is this reasonable time frame for an alternator to last?

I got over 1000 hrs out of the last Chrysler alternator on my Cherokee.
The current one (also a Chrysler rebuild) has been going strong for the last
400 hrs.

When the current one finally dies, I'm planning on replacing it with a
brand new Plane Power alternator. While my personal experience with the old
rebuilds has been OK, I've been hearing a lot of horror stories over the
past few years about bad rebuilds out of the box. I know a couple of A&P/IAs
that are running all rebuilt alternators on the bench before installing them,
because the failure rates have been so high.
