Try looking at the ignition coil there is a wire there that controlls the tachometer im thinking that that wire is loose or coroded clean connection and make shure wire is clean ,there will be a clip on the coil careful to remove the correct wire one at a time as not to mix them up . before removing wires to clean get a friend to wiggle the plug attached to the ignition coil and watch the tach to see if it dirups the opperation ok good luck and please work aroun the engine with caution when its hot and running ok bye for now

Tachometer does not work and speedometer is intermittent


Since the speedometer comes off the transmission and the tachometer comes off the ignition, they are totally separate except for the ground circuit. So check the dash ground cable, or add another one.

Tachometer not functioning


If the problem was intermittent before, probably you might have a loose connection problem with the terminal connectors. A spray of contact cleaner can help. But if it died instantly, have it serviced by a qualified technician. It might be that the sensor failed. hope this helps..

TACHOMETER WORKS INTERMITTENT


Do you have engine code showing by chance? It's possible the crank sensor is bad or the connection to the ecm or pcm to the instrument cluster circuit board needs a look. If you need schematics check out www.promanuals.net they specialize in Dodge Ram service manuals.
