Hello, my name is ***** ***** I would like to try to help with your problem. Have you done anything yet?
Expert:  Roy Scarlett replied 1 year ago.
Hello, this is Roy again. If you can follow a wiring diagram download from this site, it is a great diagram. Also check the third fuse see if it is blown. The green wiring is the circuit for the dash, lights gauges. If I can answer any other questions please let me know, I will be glad to help. If this takes care of your problem please rate me.Thanks,Roy

Hi Roy
Thank you for your help.I will try your suggestion tomorrow.
What site would I find the diagram ?
Expert:  Roy Scarlett replied 1 year ago.
Sorry. Here is the site .MGB wiring diagrams in color.cdr - Advance Auto the green wires from the fuse box and insert a test light between the fuse box and the wires (in series).Now that you have added a load (test light) you can replace the fuse without it blowing. Turn the ignition switch on (green wires are switched) and the test light should come on.Using the wiring diagram, disconnect the loads one at a time on the green wires until the test light goes out.The one that turns off the light is the bad part of the circuit.Use a 15 amp fuse while testing.

You can use a multimeter, if you rather, than the test light.
