Did you make sure the battery is connect to alternator's battery
terminal, and that it's trigger wire turns on with the ignition, with a volt
meter?

yeah the site http://minimopar.knizefamily.net/charging.html says that
"Check to see if the regulator is functioning by starting the engine
and turning all accessories off. The voltage across the alternator
field coil terminals (two small terminals, below the positive output
terminal) should be less than about 5V (roughly). Turn all
accessories on (headlights, brights, fan, rear defrost, radio, etc.)
and measure the field coil voltage again. It should be above about
10V (roughly)."

so i took the alt back up the autozone and had it tested (again) it
passed (again) but the guy said something about the machine doesnt
test the amps the alt is putting out. (which i didnt know) so it
could pass and still be bad. i thought if it passed then it was
good !?!?! so i guess ive got a lot to learn. looks like im in the
market for a new alternator.. at least its probably not the pcm.. i
dont get paid for about a week but ill bump this when i get the new
alt on.. wish me luck! and thanks for the help so far..

Bill, i checked those connections with the meter and they look good.
thanks j

6 months back I had the same thing going on with my BMW. Alternator tested
good (at Autozone, no less) but battery would not charge. Replaced the
brushes and it worked great. Did the same thing in my '95 Dodge van a month
or so later. For the van it cost me $2 and about an hour. If you are at
all handy with this sort of thing or if there is an shop around that would
replace them I would look that way before I dished the cash for a new alt.

Ok, I will try just once more then I will leave you be....

I suspect a bad ground path giving your symptoms just because I have
seen it soo many times before including my own Jeeps.

You have positive cables to the alternator which appear to work, but it
also needs a ground path to complete the circuit.

I would recommend you run a battery booster cable from the battery
negative to the alternator 'case' to see what happens to the charging
voltage as measured at the battery posts with a meter.

I then would recommend you run this same booster cable to a clean bolt
on the body of the vehicle and check the charging rate with a meter at
the battery posts.

If the charging doesn't change, then your grounds are likely ok.
