mahindra tach and idiot light

[jd250r]

I bought a 2006 Mahindra 6520 4x4. Has 140 hrs. now. Was serviced at 50 and 100 hrs. On the dashboard guages the tachometer will quit all together or jump around simultaneously as the low oil light flashes. I have checked all the fluids and all are in operating range. I think I have a short in the wiring there. Any help?

Check and reseat fuses. The fuse panel should be top left firewall under the hood. Is the tractor stored outside?
