4050 instruments and gauges

[Mark in Mn.]

I have a 4050 that started acting up by having all dash lights flashing,as well as stop light and ? lit up,and now no dash lights light up, some gauges work, oil pressure gauge does not.The tractor is low houred, always shedded.The wires look good, where do I go from here?
Any help will be appreciated.

Either lost power or ground. Get out your volt/ohm meter and start checking for power or lack of and grounds for each item not working.

Could be a failed or loose power supply or ground.

First thing I'd check would be the dash ground connection. Next thing would be wiring bulkhead on firewall.

I've checked the ground, all wires, and I have power going into the instrument box but still nothing works other than the volt meter and fuel gauge.

Have consulted your JD dealer service manager? If so did he contact D-TAC?

I did contact him and no he did not for whatever reason.

I would try again to get service manager to contact D-Tac.
