Kendall, how much to fix my speedometer? I will try to figure out how to pull it tomorrow and then get the details to get it shipped to you. Jeff
OP - Unfortunately given your description, it is a failed speedometer. VERY unlikely to be a bad ground, etc
As others have said, you can get "new" gauges directly from Autometer for all of the small gauges but not for the tach or speedo. But you DO have another alternative. We are just starting a repair service for the Tachs and Speedos. This involves replacing all of the internals (not with the OEM Autometer electroncis) but maintaining the same housing, glass, needle and face. We would like to get to a point where we can do these on an exchange basis - we'll send you a "fixed" one and you send us the bad one. Right now we need a bad speedo donor - if anyone has one, please let us know. Our first repaired tach is shipping out this week to an owner who can validate our approach.
If you have access to a ScanGauge you can diagnose. If the ScanGauge shows speed, then it is the speedometer and not the VSS.
