I am currently trying to wire up a oil temp gauge and I need a 10v circuit. What is the best way to get this? I have a LUCAS BR1303/20 lying around which i believe is a stabiliser. Is this a 12v stabiliser or does it regulate to 10v cus i think it was for gauges before?

A Smiths electric oil temp gauge?
Smiths gauges do require regulated 10V for operation. The Lucas part you listed above is a stabilizer for the cluster mounted gauges. Look at it carefully and you should find a male spade marked "B", another marked "I" and perhaps a 3rd one with no marking or possibly marked "E".
Mount the stabilizer so any text around the spade connectors is right-side-up and not upside-down. Switched power from the fuse box goes IN on the "B" terminal, 10V out is supplied on the "I" terminal. The third terminal (if present) is an earth connection. If the 3rd terminal is missing the stabilizer's metal housing must have a good earth connection.
Aftermarket gauges from other manufacturers (non Smiths gauges) typically operate off a full 12V supply and do not require the stabilizer.

I bought one of these from a chap on Ebay, a solid state regulator, works great with fuel and temp guages working from it, don't worry it's for a triumph, it's the same part......

That is brilliant. It is Smiths as you say. You also say mount it right side up. Does this mean it doesnt work upside down?

The voltage stabilizer is an electromechanical device with some mechanical bits. Its 10V output was calibrated with the circuit board installed in the metal case and mounted right-side up. If you mount it any other way, it will probably work but the calibration can be off by a bit.
The solid state device shown in the link posted by Cambiker will be a great choice if you 1) find your old Smiths stabilizer isn't working, 2) have problems mounting the Smiths unit right-side up, or 3) want a more reliable 10V source. The part in the link is being sold as if it is for a Triumph... it is not. It is a generic item. Triumphs used versions of the stabilizer that will look very much like the one you have. The eBay price is fair.
