voltage stabiliser
I am using the instrument cluster from a 82 cortina and the fuel and temp gauges are wandering about. I suspect the voltage stabiliser. Does anyone
know if they are replaceable and can recommend one.

Voltage Regulator for Cortina
They appear to be replaceable - reading the following linked page shows someone had "similar" problem and solved by buying a solid state
replacement: https://www.buysellcortina.co.uk/forums/index.php?/topic/57607-temp-and-fuel-gauge-reading-half-on-ignition/
Unfortunately I dont know what your current regulator is so cant assist in finding a replacement or a stockist.

The standard ford gauges use a 5v regulator, the following link shows an original mk5 cortina regulator which internally uses an 7805 3 pin
regulator.
https://www.ebay.co.uk/itm/321989014551
Check all the solder joints for dry joints, there is a diode which can be tested with a multimeter, and a capacitor which if not bulged should be
ok.
If all that looks in order, the 7805 is likely to be kaput and is easily replaceable for a couple quid.
If you were bothered you could replace all components (again only a couple quid on ebay) , the diode is likely to be replaceable with a 1n4001 diode,
and the capacitor would need to be id'd but is likely 40-50v and 330nF , there may be a 0.1nF cap on the regulated output, but can't see it
on the above listing pictures.
