i have a drain on the battery which ive narrowed it down to the interior light/radio curcuit/fuse.
when all doors are closed the interior light doesnt go off when ignition is off which normally points to door sensor BUT when the car is running the door sensor light is off open each door in turn an the light comes on which leads me to belive its not the sensors.

ive been told it could be the light delay relay not turning it off? does anybody know where said relay is?

also my petrol an water temp gauge's dont work at all no matter how much fuel i put in or how hot the car gets they never move! has anyone come across this before?
ive tried a set of second hand clocks with the same results.

any help will be appreciated greatly. thanks mike
