Well stripped the fuse box down and relay 7 was burned out but also the main power in once i was in there had corroded joints and this in turn had corroded/melted the distribution cable out - presumably to the other fuse box I think the majority of the problem has been caused by fumes/spillage from the battery at some time and there has been some serious burning so think the only route will be a replacement as it will take too long to patch and repair and then there is the integrity of the repair so Island 4x4 here i come (again )
