Help: reverse fuse location/owner's manual

[Mike <mac50@columbia.edu>]

Hi everyone, I'm new to the list.  I just bought an 89 Audi 100, but the 
owner's manual is missing!

The reverse lights don't work, but the bulb filaments are intact.  I'm 
guessing the fuse is out.  Can anyone tell me which fuse I need to 
check?  Or if you think something else may be wrong, please let me know.

BTW, I checked the archive, but couldn't find anything on the 
subject...sorry if its a repeat question.

Also, I found out that it will take the dealer 2-3 months to order a 
replacement owner's manual.  Is there a good substitute?

Thanks everybody!
