While browsing in order to try to find a solution to a 'rev counter not working' problem - I came across mention of 'checking the relays' above the fuses.
Does one of the relays have any connection (?) with the rev counter?... and if so which one.
My car has an aftermarket coil fitted... probably from Halfords by the label. Is this 'non-original' part a possible reason the rev counter does not work
Thanks.
