S3 temp gauge not working

Most likely cause? Sender unit or a wiring fault?

Or even the gauge?

Try earthing the wire that goes to the sender unit and see what the
gauge does. It should move to one end of the scale. If it does then
the gauge works and the problem is in the sender.
If this has no effect then look at the wiring and the gauge. You can
test the gauge with a fresh wire connected directly to the back of it
in the way ive just described.

Most likely - sender or wiring. Earthing the wire at the sender will tell
whether the sender is the fault. There is also a voltage stabiliser on the
back of the speedo which could be faulty, but if either this or the wiring
as far as there is at fault the fuel gauge will be showing the same
symptoms, as the stabiliser supplies both gauges.

Petrol gauge is fine. I'll have a good look tomorrow.

I would check the earth connection behind the panel. You will find two studs
sticking out and one of them has the earth wires connected with a knurled
nut. Undo the nut a bit, don't try taking it right off or you will drop it
never to be seen again, and clean up the connections and then wipe with a
lightly vaselined finger and retighten the nut. Cured mine but then my fuel
gauge also read slightly wrong.
BTW mind you don't damage the self cancelling on the indicator stalk.
