New Holland TC45d Instrument cluster issues

[kevin1955]

Ive been having some issues with the instrument cluster on this tractor. Recently the Oil Warning light started coming on intermittently , however there have been no real issues with oil level. Checked all fuses, relays, and wiring associated with cluster but found nothing. then the hour gauge stopped working, followed by the Tach. Forked out $530 something dollars and looked ok, but oil light came on a few days after running. Today the tach isnt working and it doesnt look like the hours are either, while Oil light still comes and goes intermittently. Ideas?
Thanks!

Have you checked all ground betw dash and chassis? Intermittent behavior sound like a bad circuit someplace. Clean and tighten.

Well, I have checked all grounds and i just finished checking all wires in loom to the giant PIN Plug. Everything is good, i checked continuity betweeen everything pertaining to instrument cluster. Looking like it may just be a faulty remanufactured Cluster. I tapped on cluster lightly while engine was running and lo and behold, the Tach slowly rose to around 900 and just sticks!
