Cheers for both those guys, I changed the battery last night and found that it made no difference.
I have already got double earths on the engine as I had a similar problem with an old vauxhall I used to have but I will check the earths again tonight.
After a bit of investigation I found the the brown wire on my passenger side head light was burnt and corroded. I replaced the sectionthat i could see but it went into the main loom.
So tonight it looks like I am repairing my loom.
If this works i'll give you guys a shout. Anoy other ideas are appreciated.
Peace
