I would do some testing first.
I'll split this topic as to get more in depth off of the bigger alternator thread.
How skilled are you when it comes to electrical trouble shooting? For those who are skilled and enjoy electrical systems I would recommend picking up one of
these. The best $99 that I have spent on tools recently. -
The main thing to look for is an autoranging clamp on DC ammeter.
Is there a chance that the wiring to the accessories is inadequate? By this I mean is the size correct? Compare the load and length on this chart -
Wire gauge table
Next we need to check grounds. If in doubt add another one. [yoda voice] Continuity does not a good ground make. [/voice] Power flows from the ground so the ground is more important than the positive wire. Well almost, since you do need both

.
If you think things are adequate there, then lets move to the engine compartment. If you have a clamp on ammeter you can check the load to see if the alternator is being over worked.
Hey! Since we are in here, How old is that battery? A bad battery can take out an alternator in a hurry.
Adding a ground might be a good idea here too, as I hear the stock engine grounds can be less than perfect. I ran a cable from one of the alternator mounting bolts to the negative battery bolt. Even just a piece of 10 gauge will work.
Does the alternator look to be mounted the same as ours? I'll check into that.
