Good day all. Noticed a problem earlier with our Mark 2 Focus. I first saw that the rev counter was reading high, and then see the temperature gauge, along with the fuel gauge, reading beyond the full marks. I had to have the dash cluster overhauled a couple of years ago (but were different symptoms) and had a reconditioned alternator last year. I also had a new battery a couple of years ago too. Has anyone any ideas what may be at fault here? TIA.
