While they might work ok on a gasoline powered sedan, the load on them is pretty high with the diesel. After going thru a couple of alternators myself, I took one to a local shop for repairs. After returning it the first time they fixed it by installing some different "heavy duty" parts and it's been working correctly for a couple of years now. Like yours the indication was an intermittent BAT light on the dash.
I agree with Rusty...
The problem with my Autozone alternator was the fact that the regulator needed to be replaced with one that had a higher set point. (14.2 instead of just 13.5)
