Hi @Devil's Advocate I really appreciate you taking the time to help me. Although the photos don't show, the cut is about half an inch long. It was way too awkward to get a photo, as I had to shine a torch as well as use my camera flash. If you have time, i will go back in the loft and check right now. I've moved the green and yellow earth bond accidentally, could that cause a danger in any way? Sorry for all the questions.
