I have a 7580 that the temp and fuel gauge are all over the place when the tractor is running and when you turn the lights on the tac bogs down I’ve cleaned the main ground cable and no difference in how they act, the other odd thing is that after I cleaned the ground cable the self test of the warning lights worked for 5 seconds and quit but it still will start with the button. Any help is greatly appreciated.

Start by unplugging the two harness connections straight ahead of the brake pedals, in the engine bay. Spray WD40 all over the prongs and re-connect them back together fully. Inspect for rust/corrosion or any wiring issues in that area.
