Like the title says my truck stopped charging and no speedo or tach but everything else works fine. Oh but no OD. I have checked everything i know but still cant get this fixed. I really cant miss two days of work so please help!!!!! Oh its a 95 2500 2wd auto.

 

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.
