TubbieScooter, many thanks for your response. I've exhausted my limited vehicle electrical skills today and have now left it with a so called expert. thanks again, BC8810.

Thanks Redhand, I did think that but I did remove all the fuses one at a time with out success. I appreciate your comment, thanks.

My 1989 90 Td CSW is on the fritz. The headlights will not turn off even when I've removed the fuses & the back light behind the speedo etc has failed. The only way I can leave the vehicle when not in use is to disconnect the battery.I have to assume someone has rewired the lights at some stage...
