Hi, For some reason my rev counter has stopped working all other dials Speedo, petrol gauge are working fine. Any feedback most appreciated.

Thanks for the link.

I had to replace the circuit board, as you see from the link, but it's worth checking the connectors are all home and clean at the back of the cluster. If you've got access to an oscilloscope you can check a pulse train is getting to the small ribbon cable we which connects to the rev counter circuit board...it should have +12v, signal and 0v.
