speedo and rev counter go of the scale and just generally go up and down erratically,I know that these are the magneto marrelli clocks which are known to be troublesome,but mostly with the lcd display, but oddly enough mine read fine. there is a listing on ebay that wil rebuild clocks for about £130 but heard not good things about then (alledgedly). Need to get it sorted cos i've been guessing my speed for about 2 years and it's doing me nut in .:nenau
