I decided I couldn't have a pint without looking a bit further . I found out which relay it was and removed for testing. When I refitted the relay everything back to normal. I should think the relay just got stuck but may have to wait a bit to find that out. I will try not to post without having a better look in future but I have had so many pulled in over the last couple of days that I don't know which one to do next . Regards, Bryan.
