I had a similar problem, replaced my alternator and all was great for a week. The reman alternator went bad and I replaced it again, which failed again, replaced it again and finally it's been good going on a few weeks and over 1000 miles now.

If you replaced it with a reman alternator this could be your problem.

Running the engine and keeping the RPM's at 2000 while monitoring voltage showed that occasionally, just for a split second the voltage would drop to around 11v, at that point in time the cluster would go nuts. Shut car off, restart and it would be fine.

If your voltage regulator is screwy it could cause a sudden dip or spike in voltage which could trigger all types of crazy warnings. I would try monitoring the voltage with the engine RPM's up for a few minutes to see if anything happens.
