Check/replace the crank sensor. It feeds information to both the tach and the charging system (computer), to tell it to charge.

And if your crank sensor checks out fine, start tracing where you lost the voltage to it.

Without a Tach signal, the PCM does not know the truck is running, thus no Charging.

On a '95 it's called an Engine Speed Sensor - mine went bad and had the exact same symptoms. Just buy it at a Cummins store & NOT the dealership. Cummins=$70
Dodge=$112

Took all of about 5-10 min to change - very easy.
