Take the gages out and check the solder joints, or find a shop that works on speedos and tachs.

I had the exact same problem several years ago. I brought it to the dealer under warranty and they called it "unrepairable". It was replaced under warranty and was around $900 as I remember...

I've heard the same information about solder joints that duboisr mentions above. Mine appeared like a short, as the tach only got a signal some of the time, so this sounds reasonable.
