I cut a section from XJ parts manual to show the two locations on the rear of the gauges... one is early and one late... location vary by VIN number.
I have replaced this piece twice with electronic ones available by searching on Google.. it seems MGs and other had this same piece and there is now a modern solution.. two wires to hook up.
I forget the actual voltage if using a meter on the back side.. but it is lower/different than battery voltage(?)...just read the Service Manual and it should be 10V...
Should first confirm that the PCB on the rear of the gauges has no broken lands...the traces for that gauge is complete...clean the contact areas with
a pencil eraser "carefully"...
