Hi. For some reason all the illumination on my rev counter has failed
The rev counter all warning lights and the selespeed indicator are ok just I can't see them at night 😡

Rev counter illumination power comes from fuse F4 in the fusebox under the dash. But the same fuse also feeds the speedo illumination and auxilliary instruments, so I would expect those to be dark as well if the fuse had blown.

So it is more likely a bulb or possibly the rev counter pcb where the multipin connector is mounted.

Removing rev counter is a couple of screws if I recall.

Thanks I have taken it out can't see any issues and there appears to be 4 screw in bulbs and none work
And you are right the speedo lights up fine so I guess it's not the fuse

Is there power at the connector? If I am reading the wiring diagram correctly, an orange/white wire carries power from F4; it appears to connect to a light blue/red wire after a splice on the rev counter side of the connector.
