    The contacts on the rear of the clock (speedo in the US) are fickle. Try disconnecting and reconnecting them. There is an excellent thread in the 348/355 section with good advice from myself and "f355spider", I think thats his name. Search on or previous posts in that section. That particular speedo thread is about 2 years old, maybe a bit more.

    Have you checked for continuity through the leads from the impulse generator to the speedo?
