1994 Dodge Dakota Won't start

My truck has had problems as of late-replaced the computer-worked fine for a month. Now it will not start-no click-nothing, lights, radio come on, but I notice the battery meter barely registers on the dashboard dial. I have a new battery, all terminals clean and good connection, checked all the visible fuses. Still nothing? Traced wires as best I could and don't observe any breaks. Could it be the alternator? Any help to what I should try next? Thank you in advance
