After solving a problem with the dip beam blowing its fuse, I have now noticed the fuel and temp gauge are not working .
All fuses look intact............looking for inspiration.

.....started to check tank wires as suggested and.............. found the issue immediately, wire had come off the spade connector.

It has the analogue dash fortunately, it does seem to have wiring issues tho....

Thanks all..............will probably be back soon.....

Old style dashes don’t normally give bother.

Suggest you check earth strap between can floor and top cover, multipin connectors under front right of cab, remove cab floor mat and tin cover check loom and l/h side dash panel near clutch pedal and oblong panel check dash loom they can rub through, all types of instrument panels normally do not give any problems, it's plug's, sensor's and wiring terminal's that can be a problem a good electrical cleaner can help but remember it will not remove corrosion .

Have your voice heard. Should the Horticulture levy continue?

A ‘yes’ is a vote for change and a ‘no’ could see the end of a statutory levy. I encourage you to consider the facts and to use your vote. At a time of immense change, the loss of a central organisation that invests in applied research for the benefit of all would be a considerable loss
