The problem that I have is that the speedo/tach/fuel all indicate in their de-energized positions. The only thing that moves/has moved was the tach. The tach orginally worked, but now does not. Is there something in common with all three or do I need to handle each one separately?
I have pulled the instrument cluster out and performed a visual as well as a physical check with a fluke. I have checked the plugs in the trunk for the fuel gauge as well as the speed plugs. Is there some resistance that I should expect at these connections or does it vary with fuel/speed? Can I use the fluke to give me a reading of speed (relative) if I connect to the sensor? I don't even know where to look for the tach.I would suppose the ignition coil, but there doesn't seems to be any other connections/loose wires, etc.
Any help would be greatly appreciated.
have the same problem?
