Instrument Cluster Problem and Alternator NOT Charging!
I have a 98 Dodge Ram 2500 w/Cummins Diesel. The instrument cluster gauges/needles recently stopped working. All the needles stay pointed to the left when the truck is started. They WILL MOVE about a 1/16" to the right.
When a diagnostic tool is used on the port, it shows NO Computer (ECM). Also, the alternator shows NO OUTPUT when connected to a battery/alternator machine!
The LCD odometer just flashes the mileage. The odometer is NOT racking up mileage when driven. Some idiot lights light up. The ones the do are random.
I checked all electrical connectors I could find under the hood and under the dash. I clean all the battery posts and grounds. My batteries are in good condition as well.
The alternator is NOT charging when the vehicle is driven. I was driving with the lights on and the battery was drawn down.
What's going on and what do I need to check out

UPDATE !! ISSUE SOLVED !!!
Replaced the Crankshaft Position Sensor. (aka CPS)

Glad you're still around! lol
Having a 12-valve, where the Engine Speed Sensor (aka ESS, not really a CPS) is only used to count RPMs because the injection events are mechanically controlled (and pneumatically, if you count the AFC), I was curious to see if there really is an actual crank or cam position sensor on the 24 valve and what it does. Found this interesting explanation...
