Wiring Help (ignition stays on constantly)

Hi guys would like some urgent help, on my mk1 1800 the ignition stays on constantly i can start the car but cant switch off with the key. i dont know what the problem is. ive tried changing the ignition switch behind the barrel. i have disconnected the plug which goes to the ignition switch and i have change the 17 number reply which clicks when i turn the key. none of this makes any difference.

any other ideas fellas?

Ive changed the fuse box and it still has the same problem. could anyone tell me which wires from the fuse box go to the ignition switch also whats each wire does. i think theres a short in the wires.

this will be much appreciated

Has some good wiring diagrams [click on the top link] , it's difficult to give an exact problematic solution unless the wiring loom is standard .

Has the loom been messed with ? Have you had the ignition switch out ? [The bit under the key] These can burn out .
