Ok so the other day I was cutting my lawn and as the grass is so big, I went over the wire by accident and now my wires are in two peices. Inside the wire is 2 wires that when I connect together and tape up there is still no sign of it working. I tried the fuse and replaced it but still no signal of life. Anyone can show me a tutorial on how to put the wire back together again?.. One is a blue wire and one is a brown wire. I connect them directly to whatever colours they are, blue 2 blue and brown 2 brown but still no luck. Also I twist them together so they do not split up and then tape each one up individually!.. Anyone able to help please?

Thanks
