Ok thanks folks I never thought that something so simple could get so complicated. I have a mate who is an auto electrical engineer so I think I might just hand the job off to him to come up with a workable scheme. Then I will post what he's done on here so we can at least have a reference for when it happens to others. I did enjoy the posts tho, not often now that we get to have a chat about bikes and the problems we come up with and the solutions that we all have that differ from each other, a fused line and a relay being just 2 examples that I had completely forgotten to even think of!
