Ok folks, this is my last resort...
Over the last few weeks, my Grand Prix (3.4 DOHC) has only been charging
intermittently. I have replaced the battery, serpentine belt and tensioner
and I have put a reman. alternator (what a silly place to put it!) and it
is not fixed, and I am running out of ideas to the problem.
It seems that the alternator when it is charging gives about 13.25-13.5
volts which doesn't sound like enough, when it's not charging, well, at
that point it's just a matter of time before bad things happen.
My questions are...
Is the voltage regulator in the alternator or a separate if separate what
is the likelyhood of it being bad?
Is there anything else that could be causing this at all? or am I going to
be doing another alternator swap out this weekend?
Are there any tests I can do to try and narrow down the problem?
Any suggestions are gratefully received, I really enjoy driving this car...

Normally the Starter shorting out does this type of thing or the horn. These
two accessories draw the most current of anything else in a car. Do A
current draw test on the starter. Most auto parts shops will do it for free.

It's in the alt.

Look for a voltage drop somewhere. The voltage you test/probe should be
the same whether testing across the batt-pos, the alt-pos, the batt-neg,
or alt-case, or engine block (neg).

I don't know if your still having the problems but, for the altenator you can start the car and unhook the negitive batt cable. If the car dies the altenator is still bad. Remanufactured alts alot of times came be put back on to the market with bad diodes and they tend not to last very long. Let me know if this helps.
