Case IH 985 (1990) "bad chip" on display problems. Any ideas

[Geeagri]

Good evening guys and gals.
Just bought a Case IH 985 super (1990) all been pressure tested and all good. Only issue I have with it is the display is electronic and says "bad chip".
Tried to find a user manual but no luck, as I thought it might be a bad earth or bad fuse but cannot find a fuse diagram.

Is that because electronic dash on 85 series?

No,not because of dash.
985 was made in very low numbers. If I remember correctly just under 200 units.
Need to check exact numbers from build records.

Ah! I see. That is low volume. Pokey little tractor if a little too light on the back end etc.

This sorted it thank you. Now I have a Amber light flashing at me and one any idea?

thats not the only problem if your engine is idling at 80 rpm

Amber warning triangle is lit on start up and goes out finally when the hand brake is released. It is linked to the oil pressure and temperature sensing circuits and will usually flash.
