Hi all. Have an 88 Tbird coupe 6cyl, and the lcd speedo is quite bright when I first start the car, however sometimes dims as I drive. Occasionally, it goes so black it can't be read. I am assuming a bad earth somewhere that gets a bit warm the longer it's active. I don't have a wiring diagram, so any suggestions where I should look for this bad earth? Behind the instrument panel? On the firewall somewhere (inside or out?)? Or in the engine bay?
Any suggestions may save me dismantling something unnecessarily. Or any suggestion as to another cause would also be very welcome.
Hi all, new member. Just bought an 88 3.8 Coupe 4 days ago. Flew down to collect, and drove it some 1,200 miles home from west of Melbourne to Brisbane. Performed flawlessly, and averaged 31.5 mpg, sitting on 65mph with the aircon on full power. Very pleased, and intend restoring this car to near as I can get to showroom condition. I'll then use it as my good "going out" car. Not a lot of them downunder in Australia, so it gets some comments.
Can any one tell me where on the 3.8 motor I might look for an engine number? I need to find it before our local transport dept. will allow me to make it road legal. Appreciate all answers.
