spedometer for 1984 733i

I recently purchased a 1984 733i. The spedometer is dead on the dash. When the lights are on, the lights on that part of the dash are also dead. What would I have to do to fix the spedometer? I know that this year of car has an electric spedometer. Is the actual spedometer dead, or is the dash bad? The computer that is mounted in the dash also isn't reading the speed. Any help would be appreciated, and thanks for your time!

sorry no help don't know much about these cars but first i would check your fuses
i picked up a manual at barnes an nobels
i'll let you know if i can figure out your problem

do any other instruments work on the dash or is the speedomoter the only one not working?

alright... my friend claims that every car can go 15 mph over the reading on the spedometer, and i say that on most cars only go like 20 under wat it says... if someone could reply to this it would help me out

The sending unit is attached to the rear axle on the differential, check to make sure it is not disconnected and the wire is not damaged.

I also have a 83 733i.
