My 1996 Dodge 2500 Ram 5.9 Cummins diesel automatic,

[Ralph MacDonald]

I am having a problem with the tachometer , it works when it wants . Of course the alternator will not charge when this happens, the truck engine will also not shift, the engine light comes on,, it's a nasty thing when this happens. The crank sensor has been replaced, but it did not help. I have had it to two garages here, but they could not help me. I live in a very small town in Nova Scotia, if you blink your eyes, you will miss it. Any help would be greatly appreciated. Thank you, Ralph.

Are you sure tach isn’t also a victim of the issue, instead of the cause?

Have you checked the alternator for AC noise?
