I bet you skipped step 1, in the book, FSM and all car repair books in print, 100 years now.
disconnect the battery neg lug first.!
oops, you blew the main fuses. (or blew up the new alt... sad huh)
cb 7 or cb3 fuses blown? CB means cab fuse.(dash box)
drains driving, i bet.
right.?
and the battery is not 13.3v to 15vdc running (good range)
bet 2:
and engine RPM is 800RPM or more at all times, right?
not 400.
the belt is not slipping or missing.
the connections are all tight
the battery cable lugs, are all clean, x4 ends. right?
no engine stated, size and number of cylinders.
as you may not know, diffr, engines sometimes have diffr ALT.
usa answer (for just 2 engines only , usa)
2.6L and 3.2 liter both have PCM generator gain control pin
and the PCM can be bad.
is the charge light glowing running, ?????
here is the proof the PCM does run the reg inside ALT.
called gen gain line.
you didnt blow EB17 main fuse that kills all .
there is the CB fuse , for alt.
There is no reset. It should charge immediately if there is power to the small plug with the key on. Check for blown charge/alt fuse in the underhood fuse box
SOURCE: replace the alternator on a 97 isuzu rodeo
from Yahoo answers
The alternator is located on the passenger side of the motor at the bottom. There is a bracket attached to the motor and the alternator. You need not take the bracket off to remove the alternator. Two bolts hold the alternator to the bracket. One bolt is on the front top of the alternator and one bolt is located on the bottom front of the alternator. The bottom front bolt is attached to the tension adjustment for the alternator. Loosen the tension screw then remove the bolt going through the tension adjustment. After you loosen the top, front bolt, the alternator should be loose enough to move side to side. Remove the top, front bolt. Now you must disconnect the alternator from the power supply. Behind the alternator is a screw with a wire attached via nut. Remove this wire. Nextly there is a series of wires with a plug on the end. It is plugged into the side of the alternator. Uplug this item. You can also access both of these from the passenger side front tire well. Something to consider is that remanufactured alternators in Rodeo's as well as the Honda Passport (which has the same engine as the Rodeo) do not work and the problem(s) associated with a bad alternator,ie; not charging, no fan blower, battery light and brake light on, still exsist after replacing alternator with reman. Use a factory original alternator if possible. It will cost a little more than a reman but will most likely save you a lot of time and headache!
Hope this helps you out!!

try checking out your blower speed control resistors. follow your power wire from blower to the resistors, to locat, should be in duct in front of blower for cooling. I hope this helps, if the resistors pack is good only think else is a bad switch

look carefully as power steering belt has to be removed and A/C if fitted,slacken bolts on power steering pump then find the tensioner bolt and slacken it off and then push pump unit back..Same sort of thing with the A/C pump but i think but cant remember but i sure this one has an idler/tensioner to slacken.

You need to loosen the alternator so the belts become slack. Look for bolts on top and bottom that attach the alternator to a bracket or the engine block. Loosen them and the alternator will move. Since the belts hook to other accessories, you may need to loosen them too. To get them back and the proper tension, you'll need a large screwdriver or pry bar to put tension on them as you tighten the bolts. I suggest you get a Haynes guide for this model that will have photos showing how this is done.
