Your rev counter is almost definately knackered!
OK i have a autoguage RPM guage, ive wired that up to the green wire that goes to the clocks, and it works perfect, showing the correct RPM,, but i wired it using the earth from the autoguage going to the chassis, could it be a dodgy eart going to the clocks?
i think u are right SafeChav, my clocks are almost definately knackered!
