One of our Cats developed an electrical fault yeterday at Combe. Al the electrical gauges including the tacho started to read much lower than normal and more interestingly, if we switched off then re-started the engine they read nothing at all until the throttle was blipped.
Any ideas? I thought it might be an earth problem (eg at the common earth behind the dash) but all seems sound there. Car drives fine and everything else works.
