It's a problem if you're needing to rely on a bad bench test to prove for warranty purposes.
I would get a voltmeter and measure voltage at the battery when the car is off / idling / revved at 2500 RPM. That should tell you more.
The alternator is definitely a player here. I thought I had it fixed, but it started doing this Exorcist crap out on the road like it did when the last alternator went bad. Checked under the car after dinner and what do you know...a new PS leak. Or a failed repair on the old one. What drives me nuts is, that's a new PS pump!
