Td5 speedo not working

Hi, I have a 110 defender td5. I have changed the speedo transducer, but this has not cured the problem. Looking at the wiring diagram, there is a remote fuse between the transducer and the under seat fuses. I cannot find this. Any ideas?? If this isn't the problem, what is the next obvious solution? Many thanks, Stuart.

there is a fuse in the dash fuse box for the speedo and other instruments

Cheers Johnlad, I have found that one, but cannot find the satellite fuse that is shown on the wiring diagram in the manual!!
