Electrical problem

or it could be the plastic ribbon on the back of the dials with the copper tracks in, i have the same with my rev counter and speedo...sometimes you have dials, other times you don't.

I just need to get a set of broken dials so i can peel the plastic ribbon off with copper tracks in it...all my sensors and woring seem ok!

That's a good point. Very easy to check if you have a multimeter!
