Many thanks for contributing to this thread. The = plot thickens! I've removed the pod, and cleaned all of the copper contacts. = The plug was not fitted properly, and it seems to have solved a few little = problems. The oil warning light no longer comes on when the headlights are dipped or = flashed, the windscreen washer pump works much better (though I don't know = why...) and the dashboard lights are brighter than they were.
 
However: The temp guage still goes up.
 
Another thing I've noticed is that the cooling fan = is not switching on at all. I know the fan works, because when you put current = across it, it will run. Thinking of putting a switch on the dash to control it = manually if I can't figure out why it doesn't switch. Any Ideas? Does anyone have = the wire colours for the dashboard on the '83?
 
Regarding the bentley manual, any ideas where i = could get it from in the UK? I have the pocket mechanic, but the wiring = diagram is missing...
 
Danke!
