1997 Honda Passport Alternator not charging

Electrical problem
1997 Honda Passport 6 cyl Four Wheel Drive Automatic

I have been working on a 1997 Honda Passport and replaced the battery and alternator and it still isn't charging. I am wondering what else would keep it from charging back up the battery. I have checked all the wires to see if they are getting power through them and they all seem to be getting power. I even tried running a wire straight from the alternator to the positive side of the battery and nothing seems to work. Could it possibly be the voltage regulator if this vehicle even has one. Anyway I would appreciate any ideas you could give me on this problem because I feel like a spent a whole day on an hour job and I don't want to pull my hair out. So any ideas would be deeply appreciated. Thank you
