763 erratic error codes

[weisyboy1]

Gday I have a 763 that periodicly every comes up with the following errors and the machine stops and locks hydraulic Engine temp out or range high Hydraulic temp out of range high Front aux not calibrated Sometimes the temp gauge goes right up sometimes it sits at the bottom or stays at normal operating position. The radiator is cold (can put finger in) and hyd pipes cold. I have replaced the aux controlled and had it calibrated, and replaced both temp sencors. This can happen one every 6 months or every 30 seconds. I'm leaning towards a faulty computer but wanted others opinions before going to that expence

I guess it is possible it's an earthing issue, the ground wires should all be black.

Yes check and clean the grounds. If you know of some one with the same machine you can try their module to see if the issue goes away.
