Nealh yes sorry was not meant to be dismissive just thought I had sorted it. Put a new fuse in, which I should have done before posting and that seemed to work. However just been and checked and looks like fuse has gone again so there must be some sort of fault somewhere. Will have a good look at wiring tomorrowSorry Gray had to dislike .
You can't come on ask a Q then say sorted without telling us the how and why, no matter how simple !!!.
