Still looking, there are a few wires that have bare wires where the casing has come away slightly. Not sure if this is causing the problem. Had a good look and apart from a few bare wires can't find much else. There's also a few bare wires on the battery terminals, don't know if this works cause a short. One last thing, while I was looking at the wired I moved the slave battery, when I moved it the live terminal sparked. Could this be the problem? I'm taking it yo a friend tomorrow so he can help me.
