190 rev counter not working

Hi Guys


My 190 rev counter is not working, I have changed it for a used one but no joy. Anyone got any ideas please??


Thanks

check the fuses for a start, then check the wiring at the back of the rev counter. you should have a live, earth and a pulsed live from the coil. assuming its a petrol 190
