You can bridge a connection between two of the fuses and it will work. Not ideal though
Mine is currently bridged
I think it's fuses 1 & 2, the 4AMPs on the left hand side
This was only a workaround in order to get a Roadworthy
What is wrong with these parts? The speedo cable should be changed for a new one if broken. Is the bulb in the rear light OK? If so, is there any electricity in the socket? If not, any fuse blown? If not, you have to trace the cable to se if any connection is loose.
