[W126 Coupe] MBCOUPES Digest, Vol 70, Issue 5

[Dan Gardner]

    Further to my last post I have been in contact with the local MBZ 
dealership.they inform me that there has been 6 revisions of the 560 
speedometer,they are quoting A013 542 3706 as the correct one for my chassis 
number..All the connections were secure I just didnt push the cluster fully 
home to ease removal.

    I think I will have to remove the new one and place it side by side with 
the old one and try and compare printed circuits.This is getting more 
complicated than I though possible

                                                                             
            Kind Regards Dan           1986 560 SEC Euro (220kw)
