[QUOTE="FISHTAIL, post: 7925682, member: 19212"] They shouldn't give you any problems if it's bad. The guys at the parts counter know that happens every once in a while. If the alternator checks out ok, then it's time to start checking connections. I had a partial internal break in a wire onetime that took me forever to find. It would cause problems intermittently depending on what kind of vibrations it was being subjected too...heh. Anyway, I doubt that's your problem, my money is on the voltage regulator being faulty in your new alternator. One of the advantages (or disadvantage depending on how you look at it) is that load testing the alt in the car will tell you what kind of amperage the thing is putting out while in the car (as opposed to a bench). The disadvantage is this doesn't necessarily let you know if the alternator is the problem....if you have a loose belt, a short in the battery, etc, the load test can fail, even though the alternator itself is fine. Whomever checks it should be able to eliminate the battery as a source of the load test failure quickly though, simply by swapping it out for another one in the shop. And a bad battery is also possible, but my experience has shown this to be less likely. Before you start worrying about what other kinds of crazy things this could be, get the alternator checked out. They are a known problem on these cars, and I wouldn't be at all surprised if an issue cropped up in one of the rebuilt units. [/QUOTE]
