1987 RHD 110 with 2.5 td. The fuel and water temp gauge were working last week. I was reconnecting the right rear brake light and after doing a test drive realized the fuel and water temp gauges are not working. I read the wiring diagram and don't see how the two could possibly be connected.

I check the fuses. From the diagram, it seems the fuel and water temp gauges run on the same fuse circuit. Not issues with the fuse. I saw the ground wire attached to the back of the gauges and then into the wiring harness. I could not see where the harness leads to for grounding. I tried jumping a separate ground wire but no difference.

Any ideas? Where does the ground wire terminate?

Thanks
