In Need Of a 1984-733i BMW Onboard Computer Wiring Diagram

[dcoyle2]

Does anyone have a wiring diagram for a 1984 - 733i BMW Onboard Computer? Right now I have no power it seems and I am trying to get it going so I can use it. I am trying to do all my own restorations and would appreciate any help anyone has to offer. I am very excited about being a Bimmer Owner and want to know everything my car has to offer. Thank you in advance. Dawn

I'll find a diagram monday if you still need it, but the likely problem is a small internal fuse in the OBC control unit itself. Wish ny memory was better but I think there's a little plastic cover you pop out for access, if not, you open the unit's cover for access.

THANK YOU so very much. The fuse Idea was perfect. However, if it isn't too much trouble could you still send the wiring diagram for reference (Monday). We are still tinkering with everything and it would make a great reference point to have it in case for some reason we get stuck again.
Also, I have another question for you. Do you happen to know anything about the A/C ? We have cold air flowing through the defrost vents on the top of the dash and the vents for the windows(on the door), but no air at all is coming out through any of the other vents in the dask or the vents for the back seats and floorboards? Would you or anyone else happen to know a solution to that piece of curiosity? If so, that would be another great help.
